There are also various smaller 'scenarios', quick skirmishes which you can use to learn the game or if you've only a few minutes to spare. The two bundled campaigns - Red Alert and Yuri's Revenge - follow on from the first game, and pitch the Allies and the Soviet Union against each other in a range of missions from small and stealthy to fast-paced, full-scale multi-unit battles. Command & Conquer Red Alert 2 is a classic real-time strategy game, first released for Windows back in 2000.
