My mates and I are thinking of getting together on this game and mucking around having some good fun... just wondering where i can download it for free?

Anywhere you get it for free you will NOT be able to play with friends. Buy the game and support developers, its a cheap game, and goes on sale a bunch.

You can get it for free, but you won't be able to play with friends.
