Mutants Revenge is Tiberium Wars mod that adds new Mutants faction to game and two sub-factions for each side of the conflict. This is probably the biggest mod making by the Polish Team...
Basing on old GDI plans mutants constructed this massive structure, upgrade center is building where mutants can research new equpiment for their soldiers.

Looks like a modern Version of GDI's upgrade center from TibSun... with out the Ion Cannon up-link, and other up-links.
