Cybernoid

when you get to an area with a lift, use up all of the bouncers and fire the
guns at the panel on the left side of the lift. a "t" balloon will appear.
collect it and the cybernoid will transform into a human form with full 
weapons, maces and a shield for six screens.

at the beginning of levels two and three, you can fill your supply of weapons
easily. empty your reserve of all the items you have left over from the 
previous level and the power up gem will appear. when you fly through the 
gem, you'll have full power and five shields.
