Sega has officially announced that Aliens: Colonial Marines is getting the season-pass treatment, which will include four post-release add-ons for the game. The first download is a mode called bug hunt, a wave-based challenge that includes three new maps.

The season pass will cost $29.99, or 2,400 Microsoft Points, which Sega says is 40-percent off what you'd pay if you bought it all individually. The first batch of DLC is bug hunt, a mode where players have to survive wave after wave of unrelenting enemies. The vanilla game includes four multiplayer modes, including team deathmatch, escape, survivor, and extermination.
