IOSoccer is a free non-commercial competitive third-person online multiplayer soccer game that offers unparalleled freedom in ball control and gameplay depth. Originally released 15 years ago under the full name International Online Soccer as a Half-Life mod, the game was later ported to the Source Engine and re-released in 2008. Since the last public release, the game’s code has been completely rewritten, new player models created, and countless new gameplay features added.
