Exerion

Exerion is a 1983 arcade game developed by Jaleco. The game combines both side-scrolling shooter and vertical-scrolling shooter gameplay, where players control a spaceship and must shoot down enemy ships while avoiding obstacles and projectiles. The game features power-ups that enhance the player's weapons and shield, as well as a unique energy meter system that affects the player's ability to move and attack. Exerion was later ported to various home consoles, including the Nintendo Entertainment System (NES).
