As with most PC games, cheaters exist in some form causing a negative experience for genuine players.
Players have reported cheaters and modification use within Titanfall already, and Respawn isn’t playing games. Respawn states cheaters will be “rooted out” shortly and has encouraged players to report cheaters.
Finding cheaters in Titanfall? So are we. We’re logging them now and they will be rooted out shortly.
