Head shots
Turn off the automatic aim option to get a good head shot. 
Otherwise, you will lock on to the enemy's body.


Airstrike in multi-player mode
A lieutenant can call in an airstrike by pressing Zoom, then pulling the trigger on 
where you want the bombs to drop. There is a ten second delay.


Beat The Uber Soldat
To beat the Uber Soldat, don't use the Venom machine gun, it is not very effective. 
Use any sniper rifle and just keep shooting at the solider. When you need to reload 
or need help, jump off the second floor thing onto the first with the Super Solider 
and go right where there is a table with health. You can hide there because the 
Super Solider won't go that far to find you. Then get a good angle and start 
shooting at the Uber Soldat until it's dead. When the Solider dies, be careful of the 
regular Nazi Soldiers.
