I was reminiscing over one of my favorite titles and searching the internet a bit and found this little gem. Probably worth checking out when the multiplayer version is released:

Renegade-X is a free First Person Shooter, being developed by Totem Arts; a group of volunteers committed to bringing the Command and Conquer FPS experience to the current iteration of the Unreal Engine. The aim of the project is to recreate and modernize Westwood Studios’ “Command and Conquer: Renegade’s” unmatched multiplayer experience. Originally set to be current generation remake, Renegade-X has evolved into more of a spiritual successor. Featuring updated gameplay, enhanced graphics, and a new approach to map design, Renegade-X will be the game Renegade should have been.
