Halogen

Halogen was a complete conversion mod of Command and Conquer: Generals being created by | Slipstream Productions in an attempt to create a Real-Time Strategy version of Halo. Microsoft had given the cease and desist order to Slipstream Productions, and has since been cancelled. Many fans were disappointed, especially after learning the progress was as far as a Beta.

Asylum
After Halogen was shut down, with less than 20% of work remaining, rather than abandon the work, Slipstream Productions has decided to modify some of the content in Halogen to fit a new original sci-fi universe "Asylum" created by one of their own. Work has already begun, and it is still being based on Zero Hour's SAGE engine.

Halogen and Halo Wars
Rumor has it that Halo Wars was directly produced because of fans' extremely positive reactions to Halogen and the stopping of the project was very disappointing to most avid fans. Halo Wars was announced shortly after Halogen was canceled, it is speculated that Halo Wars will develop the momentum of anticipation Halogen carried.
