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.
