10I disagree with all the other comments about this game. I throughly enjoyed it. Just because it is a 2d game in a low resolution does not mean people should dismiss it. I like the old school charm about the game, exploring the maps and finding different routes and weapons.

4I didn't like this game one bit. The graphics were so old school, and the gameplay was pretty bad. If you want a quality game, make sure to get away from this as much as you can...

4Aiming at the aliens was a little awkward. Computer independent gamespeed would've been nice. An OK game that could use some better designed levels. The author has made a much better, and similar game, called Meteor. I recommend you download that instead!
