Mr.Chappie i wanna play with you, you seems better then sonovabich lol. Anyway, please make exploding barrels cheaper as it helps alot in game when people think it is difficult. Moreover, there is a bug in wave 4 when the zombie spawn, there is a message immediately called ' stuckzombiedetected,bringingmetal ginder' and all the zombie gone and next wave . There is no normal zombie in any wave? I think that there should be 11 waves. Assissian should not get attention from zombie when knifing them;D. Cure infection should be cheaper as people always get it. The enginnier class's weapon's upgrade is not blalanced. The second upgrade is better than the fifth one and the upgrade after the aa-12 all of the weapons does not work, i only see a hand not a gun.
This is the order i think it should go:
1. Dogs
2. Normal zombie mix with dogs
3. Crawing Zombie
4. Flame zomie
5. Hell zombie
6. A big one - weaken with explosive and knife
7. Normal zombie mix with dog and flame - triple the amount in the second wave
8. Crawing Zombie- triple of the third wave
9. Hell zombie - triple of the fifth wave
10. Normal zombie mix with dog and flame - fifiple the amount in the second wave
11. Last big one - weaken with explosive and knife
