easy way to beat the game is to put a lot of lasers on you ship and upgrade them no enemy will get past your destructive light show. it really does work and it is easy.
its a good game i like how you own a place and you can upgrade so that you can get more money and better items also it is less like to be capture when you upgrade some stuff. I also like how it is different from some strategy games.
THIS GAME IS STUPID!! the zombies just keep attacking my base and it get destroyed and i lose every time. I would give this game 0 stars if i could but 1 star is the lowest.
