Pretty damn good!
As far as these kind of strategy games go, one with a constant rate of output, where the challenge is to distribute your income properly, this is executed pretty decently. I like how everything looks, and the camera swivels around nicely; either showing us our base, or otherwise cutting straight to the frontlines of the action. It's thoroughly more stimulating than surveying a vast stretch of land as you send out your troops one at a time.
The robot voices were too quiet, or almost too distorted for me to make sense of what dialogue was being heard on the battlefield. The music was nice, and the sound effects were great! Though I would proof-read your stuff before sending it out there...there were a few instances of grammatical errors from our Commander as he debriefed us. Seeing as how they're robots, I would find someone to write robot-like dialogue for them...flawlessly structured, elegant, perhaps with a sophisticated vocabulary...or maybe this is a joke, as the alien stuck to his face might have fried an English circuit. :P just messin' with you
I liked the idea that it shifted from robots to squid-like aliens. I think I got all the way up to 4-1, so I can't confirm if there are any other enemy variants...if not, there totally should be, because this is an entertaining game, and good games could always use a little switching up. While I put up a decent fight, I eventually get my ass-kicked on 4-1...I'll return again and again until I defeat it.
My only problem, and I suppose this could be justified in the games story through faulty, imperfect AI in the soldiers, is once my troops get up to the gates, they have no sense of target priority. They'll be blasting away at the gate while taking basic-level fire to the face until dead, and there's no way I can go "Hey! Idiots! Take THAT guy out...or die, y'know why not. You're only a Captain with an Acid Gun in front of two of our best snipers, being killed by ONE of their grunts. Stupid stupid stupid!" lol
I would hope they would go after the greater threat before moving onto the immobile target.
Still, it was an addicting time-waster, and because I have yet to reach the very end, I'll come back to finish the job. Great work! Voted 5.
