The ant is the enemy that you will meet most frequently. Much more deadly than the insect variety.

Straight out of Alien these creatures will gnash, claw and shoot their way to a chance to dine on your tender flesh. Ants are somewhat intelligent predators in that they will use their ability to walk on ceilings in order to avoid your attempts to destroy them. Beware: ants often travel in packs.

Each type of ant is a different color and fires one of the eight (or four) weapons provided in the game.

These giant robots have in their possesion an unlimited number of grenades and they aren't exactly conservative with their supply. Some models of this robot are immobile while later models will walk towards your character in order to get a better shot. Juggernauts are quite tough and can take a lot of direct hits before they shatter to pieces but unfortunately you usually aren't given a choice to run away.

These agile robots have the ability of flight. Flyers never stand still so they are often difficult to target however a steady stream of laser pulses or guided missles usually do the trick.
