Space Seeker

Space Seeker is a horizontal scrolling/first-person shooter arcade game which was released by Taito Corporation in 1981; it runs on Taito SJ System hardware, and the player must use an 8-way joystick to take control of a spaceship (which is the eponymous "Space Seeker"), with two buttons to make it fire shots at and drop bombs on various enemies (however, in the first-person areas, the joystick can only be used to direct the Space Seeker's laser cannons left and right, and the Bomb Button has the same effect as the Firing Button). At the start of the game, the player has to move the Space Seeker (which is represented by a red circle that has four white dots in it) from its base to either one of three alien bases (which represent the horizontal scrolling areas, but can fire shots at the Space Seeker to kill it on the Earth map, even while it is in its own base) or one of three Saturn-lookalike alien planets (which represent the first-person areas) - and if the Space Seeker clears an area, the base or planet representing it will disappear from the Earth map (however, if it gets killed, it will be resurrected at its base providing it has more than one life remaining, allowing players to try another area if they wish).
