4 stars: it's good it's good but I can't upgrade the characters unless I upgrade their skill and their skill price is way over what I have. when im upgrading a character it'll say I can still upgrade their level by ten but not by ones because I have to upgrade the skill. also when im upgrading the zombology thing it would be nice to see the level while I'm upgrading it. great game though
4 stars: *Game mechanic suggestions* Why is the baracade invincible? I think the game would be more interesting if something happened if the zombies could break the baracade. Maybe if you killed a boss your character could push forward to the next baracade but if you wait to long and the zombies break your baracade you have to run back to the last one. It would give the game a greater sense of progression I think. Also I think an optional free aim setting would be fun (character shoots where you put you finger instead of auto aim). Good job!
5 stars: I loved it When you upgrade it to prestige, sure it restarted to lvl 1 but at least you're prestige it's just like call of duty black ops 1 and 2 and this game is so addicted!!! I give this 5 stars.
5 stars: Loved it It's pretty fun I have been playing this for a while and I never told the creators how good this game is, good job
4 stars: Zap zombies It's a good game but it is a bit boring in some parts . Things are good but not very hard . I would have gave it the next star , it's just not that good . So I give it 4 stars ...
