Raiden Densetsu ~ Raiden Trad (Japan, USA)

Start the game by pressing Enter. You control a fighter jet that moves in eight directions using the arrow keys. Your main goal is to survive through waves of enemy aircraft, tanks, and ground turrets while collecting power‑up icons that fall from destroyed foes. The red P icon boosts your weapon to a spread shot, the blue one gives a laser, and the green one adds a tail gun. Bombs are limited, so use them only when the screen gets crowded or a boss appears. The game scrolls vertically and ramps up difficulty quickly; learning enemy patterns is key to lasting longer. If this is your first time, expect to continue often until you memorize attack sequences.
