This speedrun was slammed together in a hurry. There might be some editing errors in some of the levels

This port is a disaster. The more I play this game, the more I discover how broken it is.

Reloading a save even once, can cause the guards to become even more deaf. I don't believe they become completely deaf. I haven't tested how long it lasts or why it happens, but it just does. It's another thing I stumbled upon on accident. It doesn't appear to affect their vision. Also, it doesn't work on the 360 version.

When reloading a save, the HUD doesn’t synch up with how it was when I saved. Example, having the radar on when I save, then reloading causes the radar to turn off.

The game is patched to Version 1.02a
The guards are noticeably deaf and very inconsistent compared to the 360 version. Sometimes the guard’s deafness i inconsistent too. Also the guards sometimes glitch out or act erratically. Additionally, the guards have poorer vision compared to the 360 version. Many things are broken in this game and it tends to crash.

Smoke grenades causes the guards senses to hilariously drop.

Iceland 4:52

At 3:30, if you save at the right moment, it causes Sam to soft land instead of losing health. But that is negilible since the path to the vent is more than enough time to regenerate health if I did take damage.

You’ll see me pass through the electric transformer at 3:37. For some reason, only that one is not solid. All the others are. I even reverted back to version 1.0 and it still is not solid. The 360 version doesn’t have this issue.

Got lucky and managed to get the past the bullshit ladder guard without him detecting me. I’m pretty sure this fence jump trick will not work in the 360 version.

3:55 Holy shit, I got so lucky

5:24 no idea how I’m getting shot and not detected

Jail 4:30

3:03 This part doesn’t work very well in the 360 version

3:40 He couldn’t hear apparently

Found a new shortcut at 5:06 by rolling on the rail

JBA Part 1 11:21

In my previous run, I got the background info, medical files, and met Enrica. But that was due to my bad memory, because I thought I needed that in order to finish mission. Those are not required, so I skip all of those in this run.

Planting the bug on the roof is obnoxious because that guard can spot me if I'm not fast enough. Now, 5:50 was done on accident. It was not part of my orginal plan. I did it for shits and giggles—and it worked.

Also, someone at 6:25 on the lower floors can see me holding the utlrasonic emitter if I'm too close to the rafters.

Dayton decides to be deaf at 7:33 then stops being deaf all of a sudden.

8:43 is hilarious how Jamie just sits there

You might notice that after JBA part 1, I was supposed to get three unlocks. The missing unlock is the electronic lockpick. The electronic lockpick is or WAS in the game since it shows up in version 1.0, but you can't access unlocks since everything in 1.0 is broken as fuck. After patching the game to 1.02a, its simply not there anymore. I'm guessing they couldn't get it to work properly and decided to patch it out of the unlock screen. This wouldn't be surprising considering the many things that are broken in this game.

Sea of Okhotsk 10:37

Found a better way to elminate the crew

At 7:00, on the left, the panel to drop the two guards doesn’t work correctly in the PC version so I use the sticky cam instead

The guard at 7:43 is glitched and walks in place

Minor error at 8:54

It is very easy to get killed when jumping off the rail at 9:40

The captain at 9:47 is not a solid NPC at this time. I don’t think he can interact with Sam. The developers didn’t expect players to go this fast, so the Captain is scripted to run around the corner and disappear

Shanghai 9:43

Emile can’t decide if he wants to sit in the air or his seat

The majority of this mission is a gigantic bottleneck

Sliding off the dragon at 7:50 is really annoying to do

9:46 He didn’t see me apparently, also the light sensor for some reason was yellow even though seconds ago, it was green in that area.

10:32 lolwut

JBA Part 2 8:56

This mission is as boring as it looks

Also at 7:32, there is a guard that is sleeping in the chair behind the pillar on the right

Cozumel 7:58

Smoke grenades causes the guards senses to drop like a rock

3:24 Another example of the extremely poor senses of the guards. Also if you saw my previous run, you’ll notice that the crewmember is the going the opposite direction in this run. I don’t know what causes him to act that way. He just randomly decides to do so.

4:06 totally nothing wrong with the door on the left

6:00 is hilarious as it looks

For some reason the guard in the bomb area can’t see me through the glass door, yet the crew members in the command deck could see me throught the glass windows. The developers never picked up on this apparently.

JBA Part 3 16:13

The visual proof of bomb is randomly in one of the four computers in the server room. If you saw my previous run you’ll notice that the computer changed.

I don’t know if the the automatic hacking for the visual proof of bomb is a bug or a feature.

My conjecture is that the developers couldn't get the intended area working. The "intended" computer is the one you see at 6:13 in this run. The issue I discovered is that someone on the lower floors can see you hacking the computer—and if you are seen hacking, then it is an automatic gameover. Their solution was to give a freebie by automatically hacking the computer. It also happens in the 360 version.

But, this is all conjecture.

However, this doesn't explain why the computer is random. I don't think I'll ever find out why.

IIRC, the random computer problem doesn't occur in the 360 version.

Time to repeat the same shit from JBA 1 & 2.

Also, Enrica’s fingerprints are needed to get past the JBA 4 fingerprint lock faster

Even though the game indicates that you get three unlocks from this mission, there are only two left in the unlocks

Kinshasa 11:15

1:30 is hilariously easy as it looks. Those two guards are amazingly deaf and blind for some reason. This also works in the 360 version, just not as fast.

Then after exiting the elevator at 1:58, all of a sudden the next two guards are NOT deaf and blind. The part at 1:58 is obnoxious to do.

I got so lucky that 10:14 went so smooth

If you saw my previous run, you’ll notice that I skip the woman on the bus in this run. That is because in the previous run, my game kept bugging out and penalizing me for not saving her. Then all of a sudden, it decided to stop doing that in this run. I also did this in the 360 version just to make sure and yes, the women on the bus can be skipped without penality.

It's amusing how the smoke grenades at 10:55 cause those two soldiers to freak out.

At 11:11, lolwut, I apparently get shot somehow and got caught in the landmine blast—and I survive. All of this was not part of my intended plan.

JBA Part 4 8:04

In my previous run, due to my bad memory, I thought I needed 66% for the good ending. It’s actually 33% NSA trust for the Good ending.

Jamie’s Retina is faster for unlocking the retina lock. I just need to immediately get his retina and bolt out of there. Also, this trick works in the 360 version.

There is a very stupid bug in JBA HQ 4. Even in patch 1.02a, the game still penalizes me for firing that one mandatory bullet, resulting in a 99% stealth rating. But the even weirder part is that after finishing the level and going back to the mission menu, the game doesn't save the score, it just gives a 0% stealth score. I found this out by accident, but apparently the game uses the stealth rating on the NYC boat level and pastes it onto JBA HQ 4.

In JBA Part 4, in the high security basement, the visibility meter on Sam bugs out and fails to synch up with the HUD for some reason. AFAIK, it only happens in this specific part of the game.

The part at 7:03 is very obnoxious to do. 7:43 is not as easy as it looks

JBA Part 4 cannot be finished in a 16:9 resolution. If you try to finish it in a 16:9 resolution, the game softlocks since the SWAT team doesn't load.

There is a very nasty bug that occurs during the good ending. When the bomb is defused, Emile and his men are removed from the area and placed in a room far outside the map. During the good ending, Sam is also placed in that same room. Sometimes the AI is still active when they are moved into that room—and they can run into Sam and gun him down, causing a game over during the SWAT raid. I also found out that this bug can occur in the 360 version too.

NYC Boat 1:13

I don’t think this trick works on the 360 version.

Also, AFAIK the mission doesn’t penalize for anything except for a body being found. Even being identified as an intruder or force hacking doesn’t penalize the stealth score

Welcome to one of the worst ports I have ever seen made by Ubishit shanghai.
It is very glitchy, unstable, and inconsistent due to poor/non-existent testing.
They released a broken game and then barely patched it

Originally, I was speedrunning this game in 2007, but I kept procrastinating on and off during the years. It wasn't until 2013, that I decided to stop procrastinating. I decided to run this game after seeing prospy05 YouTube channel and was impressed by his Iceland speedrun.

Since Double Agent was developed for the 360 then ported in the most ass way possible to PC, the guards have amazingly bad senses. That doesn't mean they can't detect me, it just means that I can stomp around more often compared to the 360 version. The guards are noticeably deafer compared to the 360 version. Sometimes the guard's deafness is inconsistent too, as in some guards might have better hearing for some unexplained reason. Even though they have better hearing in the 360 version, the guards are generally the same glitchy as fuck and inconsistent guards as the PC version. The guards tend to glitch out, act erratically, and/or have problems seeing Sam even in daylight missions.

Reloading a save even once, can cause the guards to become even more deaf. I don't believe they become completely deaf. I haven't tested how long it lasts or why it happens, but it just does. It's another thing I stumbled upon on accident. It doesn't appear to affect their vision. Also, it doesn't work on the 360 version. When reloading a save, the HUD doesn't synch up with how it was when I saved. Example, having the radar on when I save, then reloading causes the radar to turn off.

You will see me save a lot since this game loves to bug out. Even in Version 1.02a, many things are broken in this game and it loves to crash.

I wanted to get 100% stealth on every level while going as fast as I can.

*01 Iceland:[04:52]

At 3:33, saving at the right moment, causes Sam to soft land instead of losing health. But that is negligible since the path to the vent is more than enough time to regenerate health if I did take damage.

You will see Sam pass through the electric transformer at 3:42. For some reason, only that one is not solid. All the others are. I even reverted back to version 1.0 and it still is not solid. The 360 version doesn't have this issue.

Got lucky and managed to get the past the bullshit ladder guard without him detecting me. I'm pretty sure this fence jump trick will not work in the 360 version, for 100% stealth anyways.

Holy shit, I got so lucky at 3:59. I just improvised this part and pulled it off

During extraction, I have no idea how I'm getting shot and not detected. It freaked me the fuck out because I thought I would get killed


*02 Jail:[04:30]

It is easy to accidentally miss the pipe when crawling out of the tunnel. Slipping past that guard at 2:48 tends to be harder than it looks

Now the shotgun guard at 3:35 apparently couldn't hear Sam whistle behind him for some reason

After exiting the elevator, I'm not sure if the guard's positons are random

Rolling on the fence was a shortcut I stumbled upon

*03 JBA HQ Part 1:[11:21]

Safe cracking is harder than it looks in the PC version since the developers did a shit job in porting the movement controls on the dial.

I don’t think I can do any better on the firing range.

Now the part of bugging the antenna was unplanned. I did it for shits and giggles and it worked.

At 7:41, Dayton apparently can't hear Sam whistling or running behind him but then all sudden decides to hear the ultrasonic emitter

The electronic lockpick was in the game since it shows up in version 1.0, but you can't access unlocks since everything in 1.0 is broken as fuck. After patching the game to 1.02a, its simply not there anymore. I'm guessing they couldn't get it to work properly and decided to patch it out of the unlock screen. This wouldn't be surprising considering the many things that are broken in this game.

*04 Sea of Okhotsk:[10:37]

Eliminating the crew on the tanker can get obnoxious at times since they can sometimes suddenly hear Sam or somehow know where a body is. But thanks to the horrible senses of the guards, this level is easier to sneak through. Despite this, Sea of Okhotsk is still a horrid level to finish. This is one of the few times I'm glad this game is so broken

Jumping off the rail got me killed way too many times than I can count.

Also, the captain is not a solid NPC at the time. It doesn't seem like he can interact with Sam at this time. Since the developers never expected players to go this fast, he is scripted to run around the corner and disappear. The sound effects even plays when I approach him.


*05 Shanghai:[09:43]

Emile can't decide if he wants to sit in the air or his seat.

The majority of this mission is a gigantic fucking bottleneck. I don't think I can scale the building any faster.

Exiting the helipad is straightforward. Now entering the building is a little bugged compared to the 360 version. You will see me hang to the right to lure the guard, but the guard can sometimes see Sam hanging even though the light is green.

Jumping and sliding off the dragon got me killed a few times.

The guard at 9:16 decides to freak out, but apparently doesn't detect me. Also this area decides to visible even though it was green earlier.

There's nothing wrong here at 10:05

*06 JBA HQ Part 2:[08:56]

Mines have to be the most boring shit I have ever seen.

Otherwise this mission is straightforward. The ultrasonic emitter part was another thing I discovered on accident. It was usefully to make Jamie go away.

Just like shanghai, the majority of this mission is a gigantic bottleneck. If it weren't for the mines, this would be a very short mission

*07 Cozumel:[07:58]

I don't know what causes that crew member dressed in white at 3:30 to leave by running down the stairs towards me or by using the door behind him. I guess its random

I like how his response to Sam rolling in front of him, is to grab his pistol but not sound an alarm.

There is totally nothing wrong with this door on the left at 4:20

Smoke grenades causes the guards senses to drop like a rock. Maybe its just me, but it seems that the smoke grenade coverage is slightly larger than what the smoke shows.

This part at 6:09 as hilarious as it looks.

So the crew member at 7:37 heard Sam stomping around but apparently doesn't care about it.

For some reason, the guard in the bomb area can't see me through glass door, yet the crew members in the command deck could see through the glass windows. The developers never picked up on this apparently.

*08 JBA HQ Part 3:[16:13]

I had to bolt out and get Enrica's disarm code before she returns to her office. Also, Enrica's fingerprints are needed for a faster unlock in JBA Part 4 but I don't think there is enough time to scan them in her office.

Then I had to get over for the visual proof of the bomb. I personally do not know what determines which computer has the proof. I think it is random. This is fucking retarded because on the 360 version, the computer that has the proof is always the same. The computer you see in this run is same one as the 360 version.

I not completely sure why/how the game automatically hacked that visual proof. It seems like that is either a bug or some sort of feature. The only reason I can think of, is that the developers noticed that someone on the lower floors can see Sam hacking the computer—which will result in a gameover. I'm guessing this is their quickfix towards that problem.

Hooray, time to repeat the same shit from JBA 1 and 2 since the developers needed to inflate gameplay time. Bottlenecks everywhere.

IIRC, blowing up the boat saves about 12-13 seconds, something like that. Otherwise those extra seconds are due to Emile being anger and blowing Enrica's head off.

*09 Kinshasa:[11:15]

The first part at 1:38 is very easy and hilarious as it looks. These two guards are amazingly blind and deaf.

Then after leaving the elevator, the next two guards at 2:03 are not deaf and blind. They love to be uncooperative. I can't remember how many attempts that took.

I don't the meeting room can be skipped or sped up.

After the meeting, Emile is very deaf for some reason. I actually can be heard if I get off too early, but after a certain threshold, Emile apparently doesn't hear Sam running up behind him.

Its really hilarious how those two soldiers at 11:05 freak out by that smoke grenade.

Somehow I get randomly shot, but not detected. Then and I get caught in the landmine blast and survive. This freaked me out because those two events never happened in practice runs.


*10 JBA HQ Part 4:[08:04]

There is a very stupid bug in JBA HQ 4. Even in patch 1.02a, the game still penalizes me for firing that one mandatory bullet, resulting in a 99% stealth rating. But the even weirder part is that after finishing the level and going back to the mission menu, the game doesn’t save the score, it just gives a 0% stealth score. I found this out by accident, but apparently the game uses the stealth rating on the NYC boat level and pastes it onto JBA HQ 4.

IIRC, the 360 version doesn't even show the stealth score at the end of the mission.

Judging by how this guard didn't react, the radar seems to indicate that the ultrasonic emitter at 4:04 went through the floor and alerted the guard on the lower floor.

The underground basement is very jarring to speedrun. The first half of the basement is a cakewalk with the second half being the hardest part of this speedrun. Also, the visibility sensor on Sam bugs out and fails to synch up with the HUD. It seems like it only happens in this specific part of the game.

The scene where the guards kill the scientists can have unpredictable results. This game is so broken, that even in game cut scenes can break. The guard can instantly kill the two scientists, or as you can see, he can miss several times before killing them with the timer still running. The retarded randomness of this part cost like 3 seconds.

The final part with Emile and his men in the bomb area is not as easy as it looks. It is really obnoxious to do because if even one person doesn't cooperate, it could potentially throw the entire thing off. The bomb area has got to be the hardest part in the entire speedrun. I spent more time on this part, then I do for entire levels. Even Sea of Okhotsk wasn't this bad.

There is also an infuriating 16:9 resolution glitch in JBA part 4. If you try to finish the mission in a 16:9 resolution, the game softlocks as the SWAT team doesn't load for some stupid reason. It gets even worse because the in-game timer is still running during the SWAT raid.

The 360 version shows that 3 SWAT members are supposed to show up, but the first one that appears is one that drives the cut scene.

And it doesn't just end there. There is a very nasty bug that occurs during the good ending. When the bomb is defused, Emile and his men are removed from the area and placed in a room far outside the map. During the good ending, Sam is also placed in that same room. Sometimes the AI is still active when they are moved into that room—and they can run into Sam and gun him down, causing a game over during the SWAT raid. I also found out that this bug can occur in the 360 version too. Now imagine a single-segment 100% stealth run.

*11 NYC Boat:[01:13]

The guard bolting out of the room was something I stumbled upon on accident. Punching Moss is faster, because grabbing him or knifing him results in a long ass scripted animation.

This mission is strange since it didn't penalize for force hacking or even being identified as an intruder. The thing is, the game gives NO indication that there is no longer penalty for doing those things. It does dock points for a body being found, but doesn’t penalize for killing or KOing.

Sam can actually be killed when jumping off the boat. Once Sam exits the door, I lose control and Sam automatically jumps off. But I got really fucking lucky in this mission. Generally, after I disarm the bomb, somehow I can get randomly detected when I run out to the door.

I guess I'm done with the PC version for now. The amount of bugs and glitches along with random awful things that can occur make me want to vomit.

Special thanks to prospy05
