Wow, this is really addictive! I love the detail you've done with this, it's absolutely supurb: the way you shoot the projectiles, the soldiers moving backwards the way their supposed to, it's absolutely great! Plus the music makes me feel like me, the aliens, are actually an unstoppable force just wandering through and annihilating the world of man. Plus the upgrades are very nice, too... and the little bonuses for all of the chivos, me likey. Especially the omg, wtf face: that just finished it off perfectly. excellent work!
