Slayer is the latest band to feature as part of Microsoft's long-running Game With fame series, which kicks into action on December 16.
An update from the band reads: "Members of the metal group Slayer will bring their attitude and gaming skills to Xbox Live to play Gold members in Slayer Mode (naturally) in Halo 3. If you're a Gold Member join us Wednesday, December 16 starting at 7:00 P.M. ET for the carnage."
If that sounds like you then here's what you need to do. Send a friend request to the following Gamertags and be online half an hour before (6:30 P.M. ET) the Game with Fame session starts.
We dare you to ask Kerry King why he's got a girl's name...
