Rush'n Attack, also known as Green Beret[a] in Japan and Europe, is a run-and-gun and hack-and-slash video game developed and released by Konami for arcades in 1985, and later converted to the Nintendo Entertainment System and home computers.

The players assume the roles of the United States special operations Green Berets (named Steve and Ben on the Japanese Famicom ad poster) who are infiltrating an enemy military base to save POWs from execution by firing squad.

The gameplay mechanics are essentially identical to the arcade version, but the Flamethrower is removed (only the Rocket Launcher and Grenades remain) and two new power-up items are introduced: a Star mark which grants invincibility and a pistol with unlimited ammo, both which are only usable for a limited period.

The NES version features two additional stages that are not in the arcade game: an airport set between the Missile Base and the Harbor, where the player faces a group of rocket soldiers at the end; and a new final stage set inside the enemy's base that ends with the player using rocket launchers dropped by enemy soldiers to disarm a nuclear missile.

The Famicom version has a few cosmetic differences with higher difficulty compared to its NES counterpart, along with underground areas in three of the levels, which are accessed via destroying specific mines that reveal ladders to the floors below.

In Japan, Game Machine listed Green Beret in its November 15, 1985, issue as the third-most successful table arcade unit of the month.

[1] Commodore User said the arcade version is "a kind of rightwards scrolling Commando [but] much better" while praising "brilliant" graphics and sound.

[17] ACE reviewed the budget re-release of Green Beret for the Commodore 64, ZX Spectrum, and Amstrad CPC in 1989, calling it an "intelligently thought out shoot 'em up with excellent graphics".
