This is the name of a well-known scene group that specialized in creating "online fixes".

For The Forest , users typically add the game as a "non-Steam game" to their library and launch it while Steam is running to enable the Steam Overlay and multiplayer server browsing.

A "Steamworks Fix" works by tricking the Steam client into thinking a pirated game is actually a different, often free-to-play, legitimate title from the Steam library.

By replacing specific .dll files within the game directory, the fix allows users to access multiplayer lobbies and play with friends who are using the same version of the fix.
