OpenRA is a Libre/Free Real Time Strategy project that recreates
the famous Command & Conquer titles.
Available mods: C&C (Tiberian Dawn), C&C: Red Alert, and Dune 2000.
These are not intended to be perfect copies, but instead combine the classic
game-play of the originals with modern improvements such as unit veterancy
and the fog of war.
OpenRA's primary focus is cross-platform multiplayer between Windows, OS X,
and Linux; however, we include a number of single-player missions, and also
support skirmish games against AI bots.
