For a game with so many players, and that is so new, I'm surprised by how few cheaters I've come across. Only two for me so far. One was someone warping from room to room as I was chasing them in a house until the exact moment I was reloading (as all my bullets were missing due to the warping) and then they stopped in front of me, shot me and vanished.
Other time was yesterday. Landed with someone else, followed them into a house (no weapons as fresh off the ground) and I'm throwing punches at them but not one of them was hitting, despite hitting the collision detection of their body.
