Respawn Entertainment have been cheaters on notice in Titanfall and also put in place a system that should help keep the fights clean on PC.
"Titanfall uses FairFight to detect cheaters on PC. Since the launch of Titanfall, we've been collecting data on people who are cheating on PC but not immediately enforcing bans. As of Friday, March 21st, that has changed and we have started banning cheaters in Titanfall.
We will be continuing to tweak the algorithm over time to catch more cheaters."
Cheaters will still be able to play Titanfall, but only with other cheaters (so you'll be able to see if your aim bot really is the best one on the market). If you have a cheater in your party and your not a cheater you'll still have to play on the "cheater servers".
