There’s quite a bit of things you can do with anticheat on and still not getting banned, like changing the movies played in the background for multiplayer lobbies, the main menu, pre-campaign launch screens, etc. One of my friends has been playing with me with anticheat on, with a modded map he’s working on. We only play custom games and forge and campaign occasionally. We have zero intention of ever going into multiplayer but it got me thinking, does playing on custom games and not matchmade games not get you banned then? Can I play single player with mods with anticheat off? I ask because I LOVE Halo 3 in third person and the one achievement I don’t have on it is Flipyap which is totally RNG based. I’ve been using my PC to just play with mods for MP and have been using my Xbox One for actual legitimate gameplay. I’m asking because it’s rather annoying to ALWAYS have to start steam to launch the game and to turn off anticheat. I fear one day I might accidentally start it with it on and play custom games or something and get banned, but my friend told me nothing has happened to him. Given this, can I play modded map files in custom games and campaign with anticheat on? I know the obvious answer would seem like a yes which is why I never questioned it, but I’d like to play Halo 3 in third person always and if I happen to finally trigger that super annoying voiceline then I’ll finally get the achievement as opposed to not with anticheat off. I just figured the answer would be no, anticheat has to be off, because people would probably cheat achievements like beating games on legendary or forcing some to load somehow. I haven’t tried it because I’d rather be safe than sorry, but if I can still play normally, just in third person, and still unlock achievements/challenges, that’d be awesome. If not, ah well. I still got my Xbox One. Just curious if anyone else plays the way my friend does: with mods, anticheat on, just does not EVER play online match-made multiplayer with modded maps… or without modded maps because he just doesn’t play matchmaking. Thank you in advance for any replies!
