You take action by controlling a Midnight Resistance fighter. Our hero fights against the Crimson Corps (a paramilitary organization run by a mad man King Crimson). Crimson Corps have kidnapped a scientist who happens to be you grandfather. So, you set off in order to eliminate the whole organization and save your relative from them. On your way, you gain a sort of coins which you can use them on an armory and buy better weapons. The world is divided into 9 levels, each one with its own big boss for you to kill.
The action is fast with plenty to see and shoot, and some of the end-level bosses are quite hard to overcome. Most of the action-packed stages are well thought out and varied, adding to the fun immensely! The difficulty level is spot-on, with the game's learning curve set at just right point and the gameplay is straight forward and fun. Note that the Atari ST port is limited to single-player mode (in contrast to the Amiga port which support co-player mode as with the original)
Although the Amiga port is the closest graphical approximation to the original, the ST conversion looks pretty good, being colorful with nice sprites and environments that look pretty much the original too. But the game here runs in flip screen mode, so gameplay gets frustrating at times.
Sound is fine here, and the game offers a nice military-style tune and lots of death n destruction sound effects but not sampled (found only in the Amiga and the arcades).
