No hacks here at all. Frankly I am shocked you would even think there was a hack from watching this video. Guy just uses his mouse wheel to change weapons. But being able to just switch weapons on the fly is just a pretty standard thing for most PC games. Why would you think switching weapons on the fly would be a hack? It honestly just needs to be added into the game anyway as fireteam has it but for whatever reason Predator does not. Itl be a good QoL update.
Aim bot? Literally nothing here to suggest that at all. He straight up misses his second shot against the FT and misses more through out the video. The shots he landed arent even hard to land. No evidence at all his aim doesnt even snap like an aimbot would.
