The story is based around the war on Nu-Earth where a group of G.I. (Genetic Infantrymen) were betrayed by a traitor General. Most of the platoon was slaughtered, but one still lived on. Collecting up the dead troopers bio-chips, this trooper then turned rogue, and vowed to avenge the death of his war brothers and kill the traitor General.
The battles are set over four levels combining different styles of gameplay. Initially you need to escape from the Nort prison in a beat-em-up (and shooting when possible) style gameplay until you find your way out and then proceed to the next levels where you fly on a spaceship and battle with airborne hostile crafts in a Space Harrier gameplay!
In the 2D levels there is quite a lot of interaction with the backdrops. You collect several items and need to operate certain spots in order to unlock doors and collect advanced weaponry and armor. Each level is full of nasties varying from human armored guards (the Norts) to flying robots. You may collect money too, in order to be spent for buying extra armor. The flying levels are the next part. Those are ala Space Harrier gameplay-style, which involves flying low and fast over Nort territory. Credits are collected for destroying incoming enemy jets and this are increasing the power of your puny craft!
Rogue Trooper is a good game and worth a look. It offers great gameplay with some good looking graphics and sound although a little more variety in details and music would have been better.
Graphics although not eye catching, look good and run pretty fluid here. In 2D platform gameplay levels, sprites are nicely designed and pretty well animated. Background scrolling is smooth too. There several details in the interior levels (but repetitive) and the flying levels ala Space Harrier look great with some impressively smooth parallax scrolling. I think a little more variety in details (especially in 2D levels) would have been better.
Sound is great, offering a lot of sampled SFX with explosions, grunts and gun-fire along with some tasty in-game music which, although repetitive, is one of the best I ever composed for an Amiga game.
