Devolver Digital has tweeted that Serious Sam HD: The Second Encounter will be released for Xbox Live Arcade on 22nd September.
The PC version was released some time ago and scored highly, in part thanks to the addition of new co-op modes that allow you to play along with up to 15 friends.
How come it's taken so long for the XBLA version to come out? According to the developers, the testing and submission process for the game led to regular delays.
