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. There are lots of people playing in multiplayer.
truly a unique mod. There are absolutely stunning effects and the gameplay is awesome. Balancing is great too, you can beat anybody with any general if you think about how to counter them, I love it. I don't know how you can create one of the best mods ever for FREE but you guys should get paid something for this outstanding work. Please keep it up because I look forward to spending many days and night playing such a fantastic mod.
