Each level has three types of enemies. The first type is the regular enemies that will be shooting at you. Second type is the areas filled with the white goo and third type is the egg. If you defend yourself from those white goo enemies, some of the goo will stick to your enemy, adding more goo to it. Also, they will turn into something you have to fight, referred to as egg monsters. When an egg monster gets hit, it will be destroyed and so will be the goo associated with it.
You have to destroy the egg cannon before it strikes Earth, and cause all the other chickens to die. Along the way, you can pick up items to upgrade your ship's weapons. Note again, it's pretty much just a straight shooter.
2. The Laser: This weapon is much more powerful than the missile. It is an energy weapon which will beam the enemy before it, and not just destroy it, but attack it. But the enemy can deflect it back at you, so use this weapon wisely.
3. The Anti-Gravity Gun: A hugely powerful energy weapon that can not only cause deflection of bullets, but also force the enemy to be knocked off the screen for a time, making it easy to work around. d2c66b5586
