Multiplayer
Want to play with friends? Here are the guides for LAN, remote local co-op, split-screen and compatible Steam games.
Most releases available here do not support online multiplayer by default.
When a multiplayer fix is available and linked to a game, its page displays an Online-Fix link to online-fix.me to download a multiplayer crack for that game. Follow its compatibility and installation instructions: it does not necessarily provide access to the game's official servers.
LAN over the internet
Connect your friends through a virtual network with Radmin VPN or ZeroTier, for games that already support LAN.
Radmin VPN: Windows. ZeroTier: Windows, Linux and macOS.
OpenRemote local co-op
Play a local multiplayer game together over the internet using Parsec to share the host's screen and controls.
Host: Windows or macOS; macOS has no controller support. Linux is a guest only.
OpenSplit-screen
Run several instances of a supported game on the same PC with Nucleus Co-op, using separate controllers or input devices.
