It's a full 3D gun game where you fight monsters from Mars. Be brave enough to fight and lucky enough to win!
Right away, choose a server and join your team. You can pick either the soldiers or the aliens. After that, you'll be in a "arena" where you have to beat your opponents and score enough points for your team. Time runs out at the end of each game. One team will win when it's gone. There are different game types to pick from, such as zombie horde, survival, and Mars War.
Have fun and good luck!
