At its core, Action Fighter is a side-scrolling action game that follows the story of a secret agent on a mission to infiltrate an enemy base. You play as this agent, tasked with gathering information and destroying key targets while avoiding enemy soldiers and other obstacles.
The gameplay revolves around movement left and right through the levels, jumping over obstacles, and shooting at enemies to progress through each stage. The game gets progressively harder as you move through the levels, adding new challenges such as tougher enemies and more complex platforming sections.
