This is a rising star in the io games. A great 3d multiplayer game where you play a little warrior box. In hordesio you have many cool features that you can use to win the other players: different kinds of weapons, asking help from flow players, multiply and more. Hordes is a bit more complicated than most io games but it is extremely fun.
How to play: chose a team. Use WASD to move and the mouse to aim. Right click your enemy and press the weapon number that you want to use.
