This is Double Agent for the Original Xbox played on the 360 through its backwards compatibility.

I think these are Individual Levels or whatever SDA defines these as since the equipment given for each level appears to be static.

The difficulty levels are: Normal, Hard,Expert, and Elite

There are 14 levels:

1_Iceland-The Ruins
2_Iceland-The Thermal Base
3_Iceland-The Foundry
4_Iceland-Sabotage
5_Jail-The Insertion
6_Jail-The Break in
7_Jail-The Blackout
8_Jail-The Riot
9_Jail-The Breach
10_Kinshasa-The Front
11_Kinshasa-The Chemical Depot
12_Kinshasa-The Old Mine
13_Kinshasa_The Canyon
14_Tanker on the way

Watch us stealthfully punch guards, break lights, and sit through unskippable interrogations. There won't be comments for all the missions since there is not much to write about.

• Iceland The Ruins:[04:27]
  
  There is not much we can do about the unskippable lambert speech. Not only that, the guard's interrogations can't be skipped otherwise the objective gets canceled. You'll see this happening a lot in the later missions
  
  
• Iceland The Thermal Base:[06:20]
  
  I suppose lambert having a hissy fit at the end could have been avoided
  
  
• Jail The Insertion:[02:48]
  
  Tangibility got stuck on the table since it decided to have a seizure.

  Setting a massive explosion isn't supsicious at all.
  
  

• Jail The break in:[03:58]
  
  Flashbangs and smokes everywhere
  
  
• Jail the blackout:[03:41]
  
  We could actually go faster after the elevator first drops but its very unreliable at times. So we decided to wait it out
  
  
• Jail the Riot[03:32]
  
  The guard at about 3:20 is scripted to die. The obnoxious part is that if you knock him out before the script happens, it apparently registers as a kill on the stat screen.
  
  
• Jail The Breach:[02:45]
  
  Why is this even a mission? There is barely anything to do.
  
  
• Kinshasa The Chemical Depot:[04:41]
  
  This mission was a major pain in the ass to do. Now Tangibility was supposed to be shot by the turret, but I guess it hates me more.
  
  
• Kinshasa The old Mine:[03:24]
  
  Sniper shots and mines detonating aren't suspicious at all
  
  
• Kinshasa The Canyon:[05:38]
  
  This mission was difficult but for all the wrong reasons. It is just a long drag through the mountains. Now at 4:00, Tangibility cannot into zipline so I had to take the controller and do the jump myself.
  
  
• Tanker on the way:[07:02]
  
  The first red mercury device appears to spawn in a random location. But the other two appear to be static, also that wiff at the end was ugly but we didn't want to start over because of it.
