Heavy Barrel (US, revision 3) — About this game
Heavy Barrel (US, revision 3) separates movement from weapon aim with its rotating arcade joystick. Keys unlock crates containing upgrades, supplies or parts of the six-piece Heavy Barrel cannon. Completing that set supplies a powerful but temporary attack before the soldier returns to the previous weapon. In a two-player game, the fighter collecting the sixth part receives the cannon, making the order of collection matter to the shared assault.
