For players who want to try out the new game before it comes out, there will be a closed alpha test starting later this month. A trilogy of games released on the Mac back in the '90s, Marathon put Bungie on the map before it released Halo on the original Xbox.

Bungie finally took the wraps off its upcoming team-based extraction shooter, Marathon, sharing a look at gameplay and a cinematic short during its showcase this weekend. We also now know the release date: September 23.
