SAVE GAME
To save a game make sure a memory card is inserted into memory card slot 1 of the PlayStation. Space Invaders only saves to memory cards inserted into memory card slot 1. The Save Game option is only available for a one-player game. At any time during gameplay, press Start to pause the game, then choose Save Game from the Pause menu. Select one of the available slots by pressing up/down on the directional buttons. Press X to confirm your selection.
POWER-UP ENERGY BAR
Power-ups are earned when you fill the energy bar in the upper part of the screen. (See HUD.) The energy bar is filled by consecutively shooting aliens of the same type. It takes four aliens to fill the bar.
If you shoot a different alien before filling the bar, the bar becomes empty and begins to fill again with the color associated with the new alien.
Once the bar is filled, you are awarded a power-up. The type of power-up is dependent on the color of the bar. When it is full, the bar will begin to flash and pulse, and the name of a power-up will appear next to it.
After the bar is filled, subsequent shots have no effect on the bar until the power-up is used.
The power-up can be activated by pressing the ▲ button. The energy bar is then reduced to zero. Aliens destroyed by the power-up count toward refilling the energy bar in the order they are killed.
If the Tank is destroyed, the energy bar is reset to empty. When the level ends, the bar will carry over to the next level.
