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.
Contra doesn't have many public models in game. In fact, there is one only. It is famous Dragon Tank. I couldn't find a better concept for this true masterpiece, in order to make this tank unique for Contra. At the end, it would be just a slight variant of this unit. So, Dragon tank got his texture and UVW map improved to fit all other China tanks in Contra mod.
