4/5
its a decent defence game. good graphics almost no lag pretty nice sound good violence and excellent interactivity.
To all people who want an easy walkthrough follow this:
Save up to buy rapid fire. upgrade it once then when you can upgrade power than rapid twice and max the power out after all the rapid and power is maxed out buy multi. If you are getting hit a lot buy many medkits. Dont buy bombs!, you shant be needing them
