Update 2 live (controller support delayed)

Make tanks deadlier Fix some random spawn bugs Boss fights' balancing Fix some graphical errors Add graphic setting options Adding tips Some general bugs

Note: due to the fact we just got to test with a controller today, it was more complicated than we thought. So we have to delay it to the 3rd update. We are also working on trading cards, badges, and other goodies.

Stay tuned :)
