Love it.
There are only a few things on Newgrounds that I truly love. This is one of them. Backgrounds were awesome. Trucking through the desert on a Heavy Tank gave me a vague feeling of glory and pride. Holding off hordes of lizards, walkers, and UFOs with a light and heavy tank by my side really conveyed a sense of camaderie in the midst of peril. AI was pretty good. I liked how the Dune Buggy slowed down for my heavy tank on the moon level (i think it was level 28). One thing irks me. Level 30 is impossible.
SPOILER SCROLL DOWN TO TRIPLE ASTERISK NOW
QONGALCHNZ is the level 30 code. That's all I'm telling you quitters. You are somehow marooned in a sort of underground cave area where literally dozens of lizard things pour at you. You have no vehicle. It's you and your shotgun against lizards, ufos, and those motherships. Seriously. This is HARD.
***(spoiler over)***
Up until that point, I loved it. Make more please!
