i find the exp thing redundant, often the higher leveled people have the better guns, in this game, it's the gun that counts. you can almost never get a kill on a rank 10 person when you're rank 1. plus, it's still really hard to go up levels, and the games should actually end, the winning team should get some awesome amount of exp and coins for winning. please + this to see if this updates are made.
Instead of having 1GP per kill, why not make it how much GP you earn from the level.Pretend you kill someone level 3.Instead of getting 1 GP, why not get 3 GP?
here is the best strategy I have come up with... put down two basic towers and 1 elctro tower right off the bat... go ahead and level them up a few times...start your first wave and finish lvling them all the way up...add a few more basics and electros...finally add sniper towers when you have the money...sniper towers are ridiculous once they are fully lvled up...try and research +damage afterwards to help with later levels...(please vote up to help others)
LOL here's a way to make a LOT of money (over some time). First, get the slave cage spell. then go to the next round, and use the slave cage on a house. But, before the slave cage hits the ground, quickly move the house away. And Ta - Da ! Everyone in the house is captured. Hope this helped :D Vote to keep this commet alive!
I wish to see some friendly fire amongst the opponents. Like zombies chasing civilians, army killing zombies, helis and explosions smashing everything in their way.... that would add nice "a city in a war" feeling.
