Sega Master System / Mark III / Game Gear
Here's a novelty - a vertically scrolling shoot em up on the Sega! Take your all-action death-mobile through six levels of laser-death with some of the best bolt-on weaponry yet seen in an 8-bit Sega game.
There's the likes of Pulse Cluster Beams (the bog-standard weapon) and Directional Shot, Web Gun, Laser Cannon and Rolling Fire (they're all special weapons)! Power chips are just the business for powering up your beam.
The fast and frenetic action of the game is what really sets it apart from other Sega games - only when the screen is jam-packed with sprites does the game slow down to any noticeable extent. At the moment, Power Strike remains the best Sega vertical scroller around.
