Raiden II is a highly influential vertical-scrolling shoot ’em up released for the Arcade in 1993 by Seibu Kaihatsu. Building upon its predecessor, the game places you back in the cockpit of the Fighting Thunder ME-02 fighter craft to repel a renewed crystal alien invasion. It introduced the iconic, screen-bending purple Plasma Laser to the series, alongside a new cluster bomb mechanic, making it a definitive and visually spectacular entry in the classic arcade shooter genre.
How to Play
Your objective is to survive through eight intense stages, destroying alien forces and large bosses while dodging dense enemy fire. Navigate your ship and collect colored power-ups to upgrade your primary weapons (Vulcan spread, straight Laser, or the bending Plasma Laser) and secondary missiles (Nuclear or Homing). Use your bombs defensively to clear the screen of enemy bullets and deal massive damage. To play in the browser, press 5 to insert coins and 1 to start. Use the Arrow Keys to move, Z to shoot, and X to deploy a bomb.
Tips for Survival
- Master the Plasma Laser: The purple Plasma Laser locks onto enemies and bends around the screen. Wiggling your ship while firing allows the beam to sweep across multiple targets simultaneously.
- Bomb strategically: The new cluster bomb spreads explosions over a wide area, which is excellent for dealing with large groups, but the classic red bomb provides a longer period of invincibility. Choose the one that fits your playstyle.
- Collect medals: Pick up the gold medals left behind by destroyed ground enemies for bonus points to increase your score and earn extra lives.
