OpenRA is a modernized recreation of the classic RTS Command & Conquer OpenRA is a project that recreates and modernizes the classic Command & Conquer real time strategy games. A flexible open source game engine (the OpenRA engine), has been developed, which provides a common platform for rebuilding and reimagining classic 2D and 2.5D RTS games (the OpenRA mods). NOTE: There is a known issue with the version of mono found at SlackBuilds.org and some terminals, such as urxvt, that affects OpenRA during build time and run time; one work around is to pass the varible TERM=xterm to the script during build and run time.
