If you guys remember, in the campaign TF141 (Task Force) was assembled of Soap, Ghost, Captain Price, and Roach along with some other small time characters. Nikolai helped Price and Soap as well.

Now Ghost roach and the rest of the team besides Price, Soap, and Nikolai got killed in the mission where you had to raid Makarov's (or however you spell his name) safe house.

Anyway, the last mission was where Soap, Nikolai, and Price went into kill Shepard, which they did. Soap got stabbed in that mission.

But they were the Most Wanted people in the world (or so it seemed). So comes the question..


What happened to those three people?

Were they found?
Were they killed?
Did Soap recover?
Did Nikolai stick with them?

I think they are in Russia.
You know because the last line in the game was by Nikolai saying- "Da, I know a place."
And he is russian.
