Developer: Ed Fries

Ed Fries programmed Atari 800 games as a teenager and later led Microsoft Game Studios, where he oversaw the purchase of Bungie, the developer of Halo. In 2010 he went back to his roots with Halo 2600, which reimagines Halo as if it had been made for the 2600 in 1982. The whole game fits in 4 kilobytes, and AtariAge released it that year.
Halo 2600 is his only game on the site. Play it in your browser below.
