Background:
Two expansion packs in one with this game. History has been a bit messed up by Einstein and time travel by eliminating Hitler. This caused the Soviet Empire to expand uncontested. The Allies have been formed and it's up to them to put a stop to Stalin. You can play as both the Allies and the Soviets in over 100 missions. Make use of everything from basic infantry to the awesomely powerful Mammoth Tanks. So it's up to you if you want to save Europe or aid in it's downfall...
