Best Way To Keep Your Teammates Alive In Lvl. 2 Mission 2
Here's a tip to minimize the risks of losing a teammate in this level, since it's filled with tons of Nazi's, and several Tiger tanks.
Avoid freeing the three SAS scouts until you've done all the other objectives aside from planting the bomb to destroy the V2. Go through the level, kill all the Nazi's, (I recommend a combo of the Shotgun and either the MP-40 or Thompson SMG), take the photo of the V2 schematics, kill Schnieder and steal the documents he's got in the room, steal the V2 film out of the projector, demolish the tracks leading into the V2 plant so the train can't escape, lower the V2, (but don't destroy it. Yet), head over and open the door to let the troops in, kill the Nazi scum that come out to play, head back outside, kill the tanks (rolling grenades under them works wonders. ) Head back into the large building you started in, go and bust your comrades out of their cells, kill any Nazi dirtbags that show up to cut off your escape, lead your troops outside, go back to the V2, plant the charge, run outside, and watch it go BOOM! Mission Accomplished.
