What are the weapons in Raiden?
Red power-ups give the spreading vulcan cannon, blue power-ups give the laser, and secondary pick-ups add homing missiles (M) or straight nuclear missiles (N). Bombs clear the screen.

Play Raiden online free – Seibu Kaihatsu's classic vertical shoot em up with vulcan, laser and screen-clearing bombs. No download, 2 player online co-op.
Raiden (1990) by Seibu Kaihatsu is one of the defining vertical shoot 'em ups of the arcade era. An alien force has invaded Earth, and you fly the experimental Raiden fighter through eight stages of tanks, battleships, fortresses and enormous bosses. It is simple to pick up – move, shoot, bomb – and fiercely difficult to master.
Two players can fly together: player 1 in the red fighter, player 2 in the blue one.
Collecting the same color repeatedly powers your weapon up; picking up the other color switches weapons.
More planes and ships: Raiden II, 1945 and the rest of the shoot 'em up collection.
Tip: a gamepad makes special moves and long combos much easier than the keyboard.
Red power-ups give the spreading vulcan cannon, blue power-ups give the laser, and secondary pick-ups add homing missiles (M) or straight nuclear missiles (N). Bombs clear the screen.
