The previously Halo-themed mod for Command & Conquer Generals might not have a Bungie flavor anymore, but the request to cease development using Halo intellectual property does not mean the project is dead.

Halogen lead Dispraiser said in an interview with GameSetWatch:

Luckily, though, everyone on our team is devoted. When I posted in the staff forums about the email, the thread was titled "What now?" not "It's over" or anything of the doomed sort. Most of our models are original units, including every structure but two, and even some vehicles. In fact, some of our most popular units, the Skyhawk, Hammerhead and Firefly, are all original units that we designed. Without saying too much, I hope everyone doesn't leave and miss the real show...Definitely keep your eyes on Slipstream Productions and the ex-Halogen crew.

So it looks like Halogen-- whatever it eventually ends up being called-- won't be Halo-themed, but fans will get a chance to play it.
