Contra is a freeware modification for Command and Conquer Generals: Zero Hour real-time strategy game and one of the first mods for this game. 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.
There are a few kinks concerning AI left to work out so it can't get a 10. But the depth of the mod is brilliant. Each general now actually feels very unique and not just a weak vanilla faction. The new units are skinned wonderfully and everything talks which is very good. I actually quite like the Chinese speaking Chinese and the GLA speaking something Middle-eastern. All in all, a terrific mod and I have tried many Zero Hour mods and this certainly pips them all to the number 1 slot. Phenomenal.
