is a video game developed and published by Jaleco. It was released in arcades on February 1983 and licensed to Taito for manufacture and distribution of the game in North America. The player controls a starship and must fire at enemies on the screen while avoiding projectiles. The game uses a pseudo-3D scrolling background, giving a sense of depth, and the player's ship has a sense of inertia while it is being controlled with the joystick.
Exerion was ported to the MSX, Family Computer, and SG-1000. Two sequels were released.Gameplay
Exerion features parallax effects and inertia simulation. The player shoots formations of bizarre alien amoeba, egg-throwing birds and Pterosauric creatures, as well as UFOs while flying over the surface of a planet. The player has two types of guns: a slow double shot (unlimited) and a fast single shot (limited).Wikipedia
