TW-Light is an open source clone/sequel to the epic cross-genre game Star Control II. Currently it includes only a combat portion, although epic adventure part that is called TW:Legacies is actively developed now. TW-Light is derivative work from Star Control: Timewarp
TW-Light is written in portable C++ and is known to compile and run on Linux and Windows (with the exception that it is still not 64-bit clean as nobody of us has access to such hardware)
