It would be sweet to have a coin-mineral/mineral-coin exchange system. Also in backyard monsters, (a game much like this one) you can have a wild mnster baiter to test your defences so someting ike that would be awesome.
Good idea, sad game. Needs upgrades, maybe reload speed, # of units killable per click, More traps, auto-firing turrets, should've added a little more before you submitted it. The levels are cool though. Needs explosions above all! Game has NO EXPLOSIONS!!! Maybe an explosion upgrade for your mouse, maybe even a little person to control runnning aound the arena shooting stuff. You also need some way to get the little orbs back to the stack instead of some guy dying and then chucking as far as his little arms can throw it an then the next guy coming along and going, "Oh, look, a ball!"
Game is really good, although there are a couple of things that need some improvement. The scope for the barett is a little skippy so you miss targets easier, I think that you should be ale to upgrade individal parts of the guns such as clip size and stuff, and i think a second game would be nice :p but beside that it's sweet, like survival mode! Keep making games.
Why doesn't this guy have a cell phone, that would save a LOT of time. "Hello, welcome to Firestone, what can i do for you?" "Hey, i'm kinda broken down in the middle of nowhere during a zombie outbreak." "I see, a tow truck will be there in 30 minutes, have a nice day!"
