Go to Multiplayer and host a newgame. It can be any connection. When you get to change the
game settings, one of the menus let's you set unlimited ammo. Start the multiplayer game
and then quit it. Load an old game or start a new one and you should have unlimited ammo,
as well as unlimited grenades. You only have to do this once each time you start the game.
