Why nobody review this game yet? This game is fun on singleplayer and even better in co-op.

You can play solo or 2 player mode.You start off with low level weapon and 1 mission.Another mission is unlock after the last one is completed.Weapon and extra health can be acquired by killing aliens such as Black Ants,Queen Ants,Giant Godzilla and many more.It's more fun when there is vehicles in the mission.You can drive a tank while the second player stand on top of you.There is more than 100 weapon available for you to unlock and each one of them has a slight advantages you can use in a different situation.You can choose from easy difficulty to INFERNO.A special weapon will be unlock after you've completed all mission with the same difficulty.You can spend a lot of time playing this game because its just plain fun.I really like this game and hope there is Monster Attack 2 with some new stuff and bug fixes.
