Gun Run is a Shooting game, your character just keeps on running and you must jump and shoot your way through the zones, destroy the mechanized dragons, crocodiles and flying creatures and pick up money and lives. You have unlimited ammo. But the game will get more and more challenging as you proceed to the higher levels. If the bar at the bottom of the screen reaches its full length you'll advance to the next level.
How to play:
Use the mouse to shoot and space bar to jump.
