CS2 Multiplayer Mod is a mod for Cities: Skylines II that allows you to play with friends over the internet or on your local network. You can host a city and let others join, or join a friend's city and help build it together.
The mod is in active development, so bugs can still turn up - report anything you hit on the Discord server.
- Cities: Skylines II (PC Version: Steam, XBox, Gamepass)
- All players need to run the same version of the mod.
- Players need also the same DLCs. Radio Station DLC are unaffected. Learn how to disable DLC: Disabling DLC
- No other mods, except the supported ones: Traffic, Road Speed Adjuster, Anarchy, Find It and Asset Icon Library. See Mods and compatibility.
- Internet play: Steam Relay needs no setup. Direct connection needs the host's TCP port to be reachable (the mod asks the router to open it automatically), IPv6, or a VPN such as Hamachi.
The easiest way is through Paradox Mods: find the mod, add it to an empty playset, enable it, and restart the game if Cities: Skylines II asks you to.
