Alien Trooper

Alien Troopers seem to be the basic foot soldiers deployed when the lesser Alien forms are ineffective appearing first on level 5. They are usually deployed by Alien Ships in very large numbers. These also may represent the majority of the Aliens as they are very Humanoid and carry advanced gear such as Guns and Armor, though they do not use the guns in game. They also have a similarity to Clone Troopers in Star Wars. There is also a Mega Alien Trooper on Level 6, as a boss and is much more of a threat!
