Sadly, any popular multiplayer game has a tendency to attract cheaters. An important part of any developer's job if they're operating one such game is how they respond to said cheating -- and Respawn seems to have its head screwed on in this regard.
"We hate cheaters just as much as you do," reads the URL for a post on the official Titanfall website announcing the game's anti-cheat system. "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."
The "ban" in question doesn't stop the cheating players from playing Titanfall, however. Instead, it locks off access to game features such as progression and the Challenges system, marks their main menu screen as being "Cheat detected" and limits their matchmaking to playing against other cheaters -- or, as Respawn puts it, "something that will resemble the Wimbledon of aimbot contests."
You'll notice that Respawn only specifically mentions PC here, not Xbox 360 or Xbox One. This is because cheating is a much bigger problem on PC thanks to the platform's inherently open nature -- there are entire businesses out there that operate by selling cheat programs to those desperate enough to pay for them. Unfortunately for the users of such exploits, in most cases the use of these programs is explicitly against many games' terms and conditions, particularly when playing on official ranked servers.
"Hopefully the aimbot cheat you paid for really is the best, or these all-cheater matches could be frustrating for you," continues the post. "Good luck."
Respawn's response to the aimbot problem is an interesting one, though not a unique one. Valve's Anti-Cheat (VAC) system can detect aimbots and other cheating software in order to ban players from participating in matches on VAC-enabled servers, but some server operators provide non-VAC servers for cheaters to enjoy as they see fit. This service is implemented in a wide range of PC games that make use of Steamworks features -- not just those from Valve. And smaller developers are doing similar things, too; Size Five Games' fun 2D multiplayer shooter Gun Monkeys also bundles cheaters together to make each others' lives miserable.
