The VAC setting needs to be turned off. So far I've used the trainer without issues and friends joined my game.
We should be safe if you keep vac off in your online settings.
Hey,
Wondering if you got banned yet? As i'm interested in using this trainer in co-op mode with a friend? I understand you have to turn VAC Secured off in your match settings before playing co-op but any more clarification would be great.
Thanks
