Multiplayer Anti-Cheat · Sons of the Forest

Keep cheaters out of your server.

MPAC runs on the host and keeps an eye on everyone who joins. Noclip, infinite ammo, free logs, endgame gear on day one. Log it, warn them, kick them or ban them. You decide.

Host-side only. Your friends don't install anything. Requires RedLoader.

Punishments

Your server.
Your rules.

Pick how MPAC deals with someone it flags. Kicked players can't jump straight back in, and every punishment can be announced to the server, posted to Discord, or kept quiet.

  • Kick or banRemove them from the game, or add them to your server's ban list.
  • WarningsKick and warn first, then ban once they run out. Warnings follow a player between sessions and worlds.
  • Log OnlyWatch quietly before you enforce anything.

FAQ

Do the other players need to install MPAC?

No. Only the host does.

Will it kick people who aren't cheating?

A lot of work went into avoiding that, but no anti-cheat is perfect. If a check gives you trouble, set it to Log Only or raise its limits.

Does it slow the game down?

It shouldn't. MPAC works in small, spread-out steps, and Discord messages go out in the background.

Does it work on dedicated servers?

MPAC is built for player-hosted games. Dedicated servers haven't been tested yet.

No excuses.

Free to download. Built and tested on RedLoader 0.8.6.
