Caliber .50 is a top-down, multi-directional run-and-gun arcade game released by SETA Corporation in 1989. You take control of United States Air Force pilot Captain Addis, who must battle his way through hostile territory after his plane is shot down in 1968 Vietnam. The game is notable for its intense action, requiring you to carefully maneuver through waves of enemies while managing your aim.
How to Play
Your objective is to survive and fight your way to the end of each stage. Use the arrow keys to move your character. Press Z to fire your machine gun and X to throw grenades. The original arcade cabinet used a unique rotary joystick to allow moving and aiming independently, so positioning is key to staying alive in the browser version.
Tips
- Save your grenades for clustered groups of enemies and heavily fortified barricades.
- Keep moving to avoid being surrounded, as enemies will quickly swarm you from all directions.
- Look out for weapon upgrades that drop on the battlefield to increase your firepower and chances of survival.
