Ha ha Thanks again for the compliments! The game is kind of like Zombieville level wise ,there are endless amount of levels with rising difficulty .You can call it a survival shooter though your progress is saved each level. The more you climb levels the more weapons you unlock and you're able to earn more money to buy them. And of course you get an overall score and we plan to implement Openfeint and achievements in the upcoming update. Didn't get to it in the first version. The initial introductory price will be 1.99 $ . Anymore questions?
