Contra is a freeware modification for Command and Conquer Generals: Zero Hour real-time strategy game. It's a big project started in 2004. It adds many new units as well as numerous new upgrades, new general's powers and buildings. It also adds new sounds, maps, bug fixes, enhanced graphics, and other effects, as well as three new generals.
Yet another asymmetric map with disbalanced start positions. You can see that 2 corners are designed for allies and 2 others - for lone players. This map can be played with the same manner as Fortress map: skilled players versus beginners. A variant with 3 players is interesting too. One player is in position for allies (he has 2 supply docks) fights 2 players who start in lone positions.
