Global Offensive supports matchmaking and leaderboards for all online game modes, provided by Steam. The provided online service offers the ability to filter by game modes, maps and a built-in Steam friend system. Valve also employs Valve Anti-Cheat, which can automatically remove and ban players from the Valve online network. To match players of similar skill levels for an enjoyable experience, the game uses a heavily modified version of Elo rating system. The PC version of Global Offensive also supports private dedicated servers that the player may connect to through the community server menu in-game. These servers may be heavily modified and can be completely different from the base game. There have been popular community mods created for Counter-Strike: Global Offensive, one named KZ Climb (Kreedz Climbing), where players complete obstacle courses that require advanced strafing and jumping techniques.
