"We're aware that a small minority of players are spoiling the Max Payne 3 multiplayer experience for honest players with cheats and hacks, and while certain issues will be dealt with in forthcoming title updates, today we'd like to make it clear that anyone using these nefarious methods will be dealt with," Rockstar wrote in a blog post earlier today.
"Anyone found to have used hacked saves, modded games, or other exploits to gain an unfair advantage in Max Payne 3 Multiplayer, or to circumvent the leaderboards," the post continues, "will be quarantined from all other players into a 'Cheaters Pool', where they'll only be able to compete in multiplayer matches with other confirmed miscreants."
All they have to do now is sell tickets. Reformed cheaters can be absolved by Rockstar, the blog post says, but second-offenders will be banished permanently. They'll also be removing invalid entries from the leaderboards.
