Question is how you will approach it though. Will it be passive like VAC, or will it be preventive?(looking at an EasyAntiCheat solution) And are you thinking about immediate bans? Statistic based bans? Also, VAC will only work on source engine games, so that wont be applicable. I can offer you some help on your AC if you'd like, just hit me up, I don't want to see this game ruined by cheaters. I have alot of experience with cheat developement and a close friend of a proficient AC dev.
