What Jimbo said. Before you play the game make sure you have the codes though. They are built in the game in the D-light(sp?) version and you can find them in sewer disc 12.
This was one of the greatest 'pick up and play' war games ever. It wasn't complicated but had great replay value. Nuke the Commies! Or the Capitalists if you played as the Soviets. I really, really liked this game.
