Kill to survive and then kill some more XD.
Graphics:Great for the free game.Maps are beautifully design and characters to.
Monsters are rely wacky and imaginative.
Audio:Sound of gun fire are awesome and music is great.
Story:There is only one camping(Jacobs quest)but you never get board because you play with different people all the time.
My opinion:Game has it charm and just suck you in.You can play with 4 classes:
Tech:A guy who hack the computers and must not die XD.
Officer:A guy who is the leader and have cool guns.
Sp.Weapons:A guy who covers your back and have even cooler guns XD.
Medic:A guy who heals all the other guys and save you all the time XD
All of them are fun to play and you never get board changing from class to class.
You look from above and thats the thing that makes games special.
Only mistake in this game is that some times you will lag for the few minutes if your net is slow.
Greatest thing about this game is price:0.00$ XD
