Game Play

The stargate itself can be flown into by the player. If a humanoid is being abducted, the player is taken to the area of the abduction. If the player has 4 or more humanoids attached to their ship, the player is Warped forward three waves. Otherwise, the stargate transports the player to the other side of the planet. Waves 5, 15, 25 etc. are Yllabian Dogfight waves, where the player is in space (no planet or humanoids) against an Armada of Yllabian Space Guppies. Waves 10, 20 30 etc. are Firebomber Showdown waves. A special 2000 point bonus can be gained by simultaneously catching and dropping off a falling humanoid as the last event in a wave once all the enemies have been destroyed.
