Titanfall on the PC is currently a playground for cheating players with aimbot. Respawn is well aware of the issue and is working to resolve it by deploying countermeasures to take them down. Software Engineer Jon Shiring has discussed the technology on Twitter.
As we reported last week, Respawn acknowledged Titanfall’s cheaters last week when it wrote: "Finding cheaters in Titanfall? So are we. We're logging them now and they will be rooted out shortly.”
Shiring took to Twitter to respond to complaints about the game’s abundance of cheaters late last night, stating that the studio does have anti-cheat software but that it is not yet in place:

@Peyman_std @DKo5 we have anti-cheat but it is not enabled yet – it will be soon. This is important to us.

He also responded to complaints that the studio just wasn’t doing enough:
@Fedora_Tipper @mYidoss @Peyman_std Whoah Whoah. We ARE catching them. We are not yet ENFORCING it.
