Take Nick Arnold to the restroom:
On the first level, the second mission is to rescue Nick Arnold. Immediately after this is done, fly to your base and turn left. There should be a co-pilot landing zone and a little shack. The shack is an outhouse. Land there and Nick will use it.
Look in the south-eastern corner of the Crimea strike map to find Santa Claus and the reindeer getting ready to depart for the holidays. Shoot the sleigh without hitting Santa or the reindeer to receive an extra life.
On the level where the reactor blows up, destroy all the buildings on the radioactive rivers, and inside some of them there are power-ups, like the super-gun.
Also, if you destroy the big mansion, then elvis comes out and goes 'uh-huh-huh' when you shoot him.
