Gunmaster is an action game developed in flash by Jason Reinsvold. The gameplay seems inspired from the Heli Attack series, except that the screen doesn't scroll. You play as a commando that must survive as long as possible against ennemies, helicopters and planes shooting at you missiles, bombs and bullets. A, D to move, spacebar to jump (press twice for double jump), E and R to throw grenades, 1,2,3 to change weapons and the mouse to aim and fire.
