at first i played the game and went wow this is so easy but then those up and down circles came and then i was like crap. Simple but challenging that's what makes it a great game
LOL when i did quick match i did juggernaut and the i thought i was playing online so i killed the juggernaut and started camping and like no one touched me but when i died i got right in front of the guy and started shooting but he never hit me XD
Awesome game dude but it could use waves and continues because i forget to upgrade but other than that its rad most of time the screen is rumbling which gives you the feeling of whoa wtf is going on and theres like bombs everywhere its just amazing how cool it is.
