Rush'n Attack (Green Beret) is a legendary side-scrolling action game by Konami. Set during the Cold War, players control a special forces operative infiltrating an enemy base to destroy a secret weapon. Armed primarily with a combat knife, you must steal weapons like rocket launchers and grenades from enemies to survive. The game features six challenging stages filled with soldiers, paratroopers, and landmines. Known for its high difficulty and iconic soundtrack, it is one of the 'Big Four' of early NES action games alongside Contra and Castlevania.
