Halo CE Anniversary is being developed in conjunction with Timeshift developer Saber Interactive and Certain Affinity, known most recently for their work on the second Map Pack DLC for Halo: Reach. Anniversary uses the Halo: Reach engine to present an updated look for the original campaign, as well as a Classic mode featuring the original assets from Halo: Combat Evolved.
Six multiplayer maps from the original Halo: CE are making the jump to Halo: Combat Evolved Anniversary. Multiplayer will feature the full suite of options that players have come to expect from the series - including Firefight mode.
Expect additional details on Halo: Combat Evolved Anniversary at this summer's Halo Fest, being held at the Penny-Arcade Expo from August 26th through the 28th.
