What game is this?

A couple years back I remember playing this games storyline, and there was this mission, im pretty sure it was in the snow, where you start outside of a wreck ship and you go in to look for a bomb. Then when you find it i thnk you get trapped in a room with some gas and your teamate dies. That is the best explanation i can give of it.

I also think it was kind of like ww2 era maybe not, I faintly remeber that the guns were like ww2 type guns dont fully remember though
