Big Chill - He can glide after jumping, and, while in the air, fire down ice attacks in the form of a beam.

However, Echo Echo cannot enter small spaces in the game. When combining the clones as platforms and his double jump, Echo Echo has an extremely high jump. They also expire and fade after a short time, but their disappearance will not harm Echo Echo himself. They have all the weaknesses of a character, that they cannot be placed on hazards, and will be destroyed if hit by an enemy blast. The clones can also be jumped on and used as platforms, and the clones can be used to obtain orbs.


This prevents him from easily overtaking them from a distance, though Spidermonkey's projectiles do fly faster. The webbing shots have a certain recharge rate, which is equal to that of enemy shooters.

Spidermonkey - Shoots bits of webbing from his tail that act as long range projectiles, which can cancel out enemy blasts.As the largest alien in the game, he can be hit by enemies who are a level higher than he is, except when ducking down to attack. He is shielded from enemy attacks while he performs his own, though this is temporary at best and only useful when well-timed. Humungousaur is useful when attacking enemies on a lower plane, because he can jump down on top of them and destroy them without harm. This makes him one of the only aliens who can destroy crates beneath him, along with Big Chill and Cannonbolt. Humungousaur - Destroys projectiles by doing a ground pound that can attack both ways, though with very short range.Swampfire moves backwards slowly when shooting and cannot move freely. When an enemy is firing at the player, one fireball counteracts only one enemy shot, so there is a limit to the protection of the flamethrower shield. The "shield" is actually many fireballs that are fired rapidly to create a flamethrower affect. He will hold and keep firing as long as the spacebar is pressed and holding it down will act as a shield that can hold back most offenses, though it has no effect on any threat from above, below, or behind. Swampfire - Destroys projectiles by using fire balls and can jump very high.To beat the level, you should reach the goal. There are 13 aliens, each with an easy and a hard level.
