The Halo 4 Crimson Map Pack dropped this past week, but players are reporting that they are being banned for following instructions from Microsoft.

The game's official forums are full of furious users that downloaded and attempted to play the pack, then were getting locked out from games and finding their accounts had been banned from some of Halo 4's online features.

A forum moderator released this statement:

“We are not permanently banning players for previewing or purchasing the Crimson Map Pack. We are currently investigating the recent reports of permanent matchmaking bans.

“We will provide further updates tomorrow. Thank you for your patience.”

In other words, thanks for calling, please leave a message, and we will get back to you. Have you been banned? Let us know if you're getting the Halo flavored shaft.
