improvement for Old Vegas level.
rough time 14:51

as soon as I drop out of the helicopter I run as fast as possible not waiting for my team. 1st Tango spotted and the 1st to be eliminated. I head inside the corridor where you can see 1 Tango behind a broken window but there are 2. I kill the visible that causes the other to retreat for cover which I exploit that by climbing inside without getting shot since I'm completely venerable during that animation. I chase the Tango retreating strangely my shots keep missing by an inch. after the checkpoint I reach for the left where 2 Tangoes are usually chatting off guard while 1 patrols outside balcony but sometimes they react to gunshots and are on guard. easily taken care of anyways despite getting to lowest health point but never did I get killed there so its expected. I climb the ladder anticipating 1 sniper ready to scope me but since I'm very close usually I will get hit but nothing deadly so I fire back. then switch to a sniper rifle and snipe another sniper on the balcony ahead before he gets to snipe me (sniper redundant). moving on the 2 Tangoes from below came faster then I expected and rarely do my shots miss from hip but it happens. thankfully I didn't killed surprisingly they were close funny how the AI can sometimes suck horribly bad). finally one covering behind the air duct and he is out. although I it is tempting to slide or slip down the ladder for faster way down but for weird reasons they made that even at that height it would not hurt but instantly kill (I guess gravity is much harsher). I switch on thermal goggles for clearer vision because of the glass reflection to kill 1 Tango. fasten the rope then immediately throw flash bang before taking cover to stun 3 Tangos in good covering place. while I head down stairs there are Tangos climb up on the side so I can ignore them and let my team do their work. inside are 3 Tangos but fortunately one is far away and behind obstacles where I simply take out 2 them and head up stairs to the end section.

1 Tango on the roof shot then I fasten the rope from right since the left is much slower bouncing of the wall. here it triggers an ambush in an open area an advantage for them over me where multiple enemies appear especially 1 sniper that is extremely dangerous. what I did is take out the only 1 on the otherside that can kill me quickly then run off before the rest arrive. on my way I take out one popping out of the corner in close kill. round the corner to the left is 1 Tango in the clear which I pause a moment to him take out. while strafing I'm anticipating for 1 to come out of cover for quick kill then take cover to be safe from 2 Tangos ahead. throw flash bang then head up stairs to clear the area. reaching to my target for a rescue attempt, I take down 1 then throw flash bang just in case hoping the stun would last long enough. climb the ladder then fast upside down. here I was very lucky not to get killed up close. I take out the rest but unfortunately my clip emptied as soon as I killed the last 1 which wasted about 2 - 4 seconds. I breach in only to find 1 survived. here I was waiting for my team to send them at the door but 1 was far behind so I skipped that but strangely 1 team squad went inside to reach me instead going back which never happened before. this alerted the Tangoes which I thought was unfavorable but then went ahead for an extremely risky move. in this area there so many Tangos up and down where they sit in good cover some armed with shotguns and magnums that can shot me. if that isn't enough for you even if I manage to skip them then comes 2 Tangoes that are on your way which also can kill you at close range. this part was so difficult and random at times almost all my runs got killed at that area. hence this means I was very lucky which what I was hoping for but far reached my wildest expectations that I was able to walk through without delay and especially the flash bangs worked well. I move on to another similar area but less dangerous than before. again I use flash bangs but 2 this time then safely traverse through slot machines taking out anyone on my way and reaching another end section.

In the garage the Tangos have the upper hand in covering so I take it careful instead of dashing through which would kill me. around the corner is an turret waiting to tear me to shreds so I really need to take cover. I use flash grenades as well shoot extinguisher for cover to take out as many as possible. ahead to the corridor I threw a flash for safety measures. At the end there is a Tango on the right hidden and on the left are Tangos behind cover. 1 flash to take away for Tangos immediately then I head for the door on left. inside is a shotgunner so quick kill is necessary. I head out left there are 2 tango plus 3 more will spawn shortly. unfortunately they spawned only few seconds after the flash bang but I took care of them with another flash bang. here comes a tricky area to cope with plus with being low on ammo. 1st major threat is the sniper I deal with then I send my team since its too dangerous to go alone. also I crouch here to avoid the 2nd sniper deadly shots. my team did very well in this part thanfully since they usually take way more time to react.

a quick reload before heading out. I quick scope those 2 harassing a hostage before she gets killed. here I have to protect a civilian which isn't really difficult since she doesn't act stupid by going out in the open. I take the easier route by sticking to left for cover since most Tangos plus a sniper & turret are out on the right. I wait for her to open the locked gate. I skip being stealthy and let my team breach the door since it takes ages for the guard to come out. inside the warehouse I send my team in then immediately the other door to cover more area. inside the office are hostages but since there is only 2 Tangos I didn't bother with stealth tactics. in another warehouse I use the same tactic as previously stated. at the end I rescue the hostages and that is it for this mission.
