About Bio-Ship Paladin

Bio-ship Paladin is a 1990 horizontally scrolling shoot 'em up arcade game. It was later ported to the Sega Mega Drive. While the game is essentially a standard horizontally scrolling shoot 'em up, it has an innovation that makes it unique in the genre. The player flies a spaceship (specifically, a bioship) which has the standard forward guns to be found in all horizontal scrollers, but it also possesses a weapon that can be manually targeted with a crosshair, in the same manner as in the game Missile Command. This allows the player to fire in any direction with pinpoint accuracy, and adds an extra level of strategy to the game. The game saw an almost arcade perfect port on the Sega Mega Drive. What few changes there were actually enhanced the look of the game such as added parallax scrolling backgrounds in level 2.

What the press said at the time

Sega Pro Issue 36

September 1994

51%

“Satisfactory two-player shoot-'em-up with cool sound and stunning level guardians. It slows down when there are too many sprites on-screen and it's pretty easy.”
— Sega Pro, September 1994

Before you buy

Among Japan-only carts this one is priced above about nine in ten, and it is valuable enough to check carefully. A Japanese Mega Drive cart has a notch on the left and ridged edges, and a flat Western-style shell with a notch is a repro sign. For a copy at this price, ask for a photo of the board. Japanese cartridges are a different shape from Western ones and do not fit a Western console without an adapter or removing two plastic tabs in its slot.
