Fairly good game.
It didn't stray horribly outside the usual defense genre formula, but the way it was presented was very nice. The most notable thing about the gameplay was the incorporation of the AI partner. Adds more strategy to your battle-plan, and also had the very nice touch that it took them a while to get familiar with a weapon. I'm not sure exactly why some people are offended by this, obviously it's a (heavily) exaggerated effect of the drugs, used for comedic effect or something of the like. One thing I would've preferred is a way to repair your fortress at the cost of money, but it's not a major concern because you can continue from just about anywhere, and most damage can be avoided if you hurry on advancing your weaponry.
Overall: 9/10 5/5
