Really difficult to beat the final boss, but once you get a hang on his patterns you can manage, best weapon load-out is all points to dumb missiles. It was a very rewarding victory.
You know, if you didn't have to pay money for everything and it was improved just a bit, it would be my favurite game. But you do have to pay for everything, plus you hae to wait almost an hour to heal your miscrits, the game is currently so bad with this that I can only give this a 1/5 rating.
make sure your mouse focus is in the game... ive heard that chrome and tabs makes it act a bit goofy. not sure if that helps.
