Sewersoft presents..... STEEL OBJECT OF THE GAME To collect 8 cartridges around the complex and to activate the cartridge slots by de-activating the 8 active terminals, allowing the cartridges to be inserted into the cartridges slots. The 8 cartridge slots are all located in one room somewhere in the complex. When your droid is near to the cartridge room you are warned by the proximity alert in the centre of the score panel. THE SUB-GAME To enter the sub-game, push the joystick up at an active terminal (indicated by a yellow light). Once in the terminal, the object is to shoot the data-bus on the right hand side of the screen within a set time limit. This is made difficult by rotating drivers in front of the bus. The drivers must be shot away by continuous laser fire. Also, the piece fired from the drivers must be avoided as they deplete the timer in the top left of the screen. As well as the pieces of the drivers flying towards you, occasionally icons will appear. There are four of these icons, and to use one, simply let it float into your cannon. The coloured icon with and 'R' on it will enable rapid fire if collected. The metallic looking 'S' icon will slow up your cannon for 5 seconds, leaving you vulnerable to the flying debris from the drivers. The coloured 'D'-shaped icon will decrease the timer by 10 seconds, resulting in your having less time to destroy the bus, and the last icon, a metallic bullet-shaped object, will increase the timer by 10 seconds. If you fail to complete the sub-game, your droid loses some of his energy supply. Each time you complete the sub-game, a cartridge slot in the cartridge room is activated. Then you find the room and insert the cartridge you have collected. Up to three cartridges can be carried at one time (shown at the bottom of the panel). CARTRIDGES Cartridges are purple, and are found in housing magazines which have a red light on top of them. FUEL Re-fueling can be done at re-fueling points located randomly around the complex. These are identified by the oscillating graph on their screens. Pushing up on the joystick and pressing the fire button replenishes energy, pushing down and pressing fire deplenishes it. Energy costs you score. Warnings appear on screen when your energy gets too low or too high. TERMINALS These resemble computer terminals, and have information scrolling on them. If the light is yellow, it is active, if it's red then it's inactive. DROIDS The droids found throughout the complex have different characteristics and strengths. Some retreat, others continue to bump you, and some bounce off you and fire a laser at you. The different types of droid will become apparent during the game.
