OBJECTIVE: The aim is to shoot and destroy the enemies while avoiding being hit. Watch your life line. Once it reaches zero you die and must restart the level plus you lose all your power-ups.
Make your way to the exit (typically to the far right) to beat each level. Pickup power-ups to use them. Use the 1 - 5 keys to select which power-up to use. The bottom left indicators show how much of each power-up is available. Your default gun is for unlimited use with a slight recharge time. Activate switches when available to open doorways and shut down lasers.
