Joystick: Use the 4-way joystick to direct Monster Fighter around the screen. When the Warp Zone in the centre of the screen starts flashing white, move into it to switch worlds.
Firing Button: Use this button to make Monster Fighter fire his gun at the enemies, or, if he's in Maze World, lay a time-delay bomb. Each time he kills an alien in Maze World, his bombs get stronger, which makes it easier for him to blow himself up; however, if he dies as a result of being blown up by one of his own time bombs, their power will be reset.
1 or 2 Player Buttons: Push these buttons to begin a 1 or 2 player game.

Monster Fighter
The protagonist of the game. You must use the 4-way joystick to direct him around the Space World, along with the Firing Button to make him fire shots from his gun at the Berobero. If he kills three identically-colored Berobero in a row, a mystery alien will appear on one edge of the screen and start making its way towards the edge that is on the opposite side of the screen. When the Warp Zone in the centre of the screen starts flashing white, he can move into it to warp to Maze World and lay time-delay bombs.
