Respawn Entertainment told us they had been keeping track of hackers since Titanfall's launch, and now they're taking action. However, traditional bans would be too normal, too pedestrian for their liking. Instead, Respawn is banishing PC hackers to a place where they can only play against other cheaters, and if you see the "FairFight cheat detected" message, you're in trouble.
If you as a cheater see this message you can keep playing, but you'll only be put in frustrating cheaters-only matches. Aimbots and other hacks will dominate these games, but Respawn has no sympathy for you.
"Hopefully the aimbot cheat you paid for really is the best, or these all-cheater matches could be frustrating for you. Good luck," the official site states. They also say these matches will "resemble the Wimbledon of aimbot contests", which is pretty amusing.
The site FAQ also explains that if you're partying with a banned player, the whole party will be treated like it's banned--there's no out for cheaters by just hiding out with regular players, so tell your friends not to do it. You won't be "permanently tainted" for playing with a cheater friend, just banned from normal play while they're in your party.
This is only in effect for the PC version of Titanfall at the moment, and it may not come to Xbox One. Hacking is much more difficult and much less common on console, and the issue shouldn't really be widespread. Titanfall launched on PC and Xbox One earlier this month, and the Xbox 360 version has been delayed until April.
