This mod is an incredible mod. When you join a game you have a choice. You select what position you want to play and what team you want to play on. You have, of course, one goalie per team and as many players on the field. You fight for the soccer ball and try to out score the opposing team. There are NO weapons of any sort. Just your feet and a tackling ability. The controls are simple. You move with W, A, S, D and you kick with LMB (Left Mouse Button). There are more things you can do in the mod that we have yet discovered. Other than that the mod is very fun and if wanted you can play with the built-in bots offline!
