Dark Sun - Shattered Lands is an RPG developed and published by SSI.
Apparently, Data East was working on ports of the game for Sega Saturn and Sony Playstation, but both ports got cancelled.

The game is based on the Dark Sun campaign setting for AD& D. It takes place on the fantasy world of Athas. Athas was once peaceful and pleasant - until wizards found a way to increase their power by draining the planet's energy. The let to plant life dying, seas evaporating, the sun transforming into a crimson fireball, and Athas becoming a desert world. The wizards then gained control over the land, becoming sorcerer-kings and enslaving most of the population. One of such kings, Tectuktitlay, rules the city-state of Draj. By his orders, hundreds of slaves are sent to a battle arena to find monsters. You take control of a party of four who have also been imprisoned and sent to fight in the arena. Your initial goal is, of course, to escape. However, you learn that Tectuktitlay plans to raise an army in order crush the few remaining independent villages out side the city states. So you need to find a way to bring the villages to unite to be able to fend of the army of Draj.

The game is played from a top-down view. You move only the party leader when you're not in combat. Combat is turn-based and uses the same view. Dark Sun follows the AD&D rules regarding stats, fights, magic etc. You can talk to people via multiple choice dialogues. You often have the option to tasks and conflict in several ways, violently or not violently. The game allows you to create your own party, but there is pre-made party available for a quickstart.

Super Turrican is a platformer and run'n'gun developed by German company Rainbow Arts and published by British company Imagineer. It was only released in Europe. A US release by Seika corp. was planned, but got cancelled. The game is not identical to the SNES game of the same name.

Super Turrican combines levels of Turrican and Turrican II on the C64 with several new levels. The basic gameplay stayed the same. You can jump, run, kneel, shoot and turn into a wheel. There are two special weapons, a line shot and a devastating megablast. Both are limited in numbers, but you can get additional by collecting power ups. When you turn into a wheel, you are invincible and you can place bombs which explode after a few seconds. Unlike the original Turrican, you can stay in wheel mode as long as you like. There three main weapons in the game, a spread shot, a rebound (shots bounce of from surfaces) and a laser (powerful, but only shoots straight). Holding down fire will activate a surround shot which you can rotate around your character. While the original Turrican had a time limit, Super Turrican has none. In return, Super Turrican has no checkpoints, you have to start the level from the beginning after loosing a life.

Alien Sydrome is a shoot'em up developed by Sims Co. and published by Sega. It is based on the eponymous arcade game, but not a straight port of it.

The story is actually a sequel to the arcade game's. Five years after the events of the arcades version, the aliens return and infest a spaceship called Dagal. Ricky and Mary, the heroes from the original game, come to the rescue.

The formula has not been changed compared to the original. You go through each level in order to rescue hostages.The game uses a top-down view. Aliens are spawning constantly and you die on one hit. You have a gun with infinite ammo and you can pick up other weapon which are place on the walls. Once ouy have rescued enough hostages, the exit will open and you can leave the level. There is a time limit to beat each level, and you have to fight a boss before reaching the next level. the graphic sets, enemies and level layouts differ from the original game. Also, you can call a level map which shows the position of all remaining hostages at any time, while you had to pick up an item for that in the original.

The defiler's endgame was underwhelming.

Now you're on the moon Hi-Eco-Le and need to earn enough money while avoiding the killer, in order to buy a spaceship and shake off persecutors once and for all.

You can buy and sell different goods at these places. You can also accept errands like shipping a certain amount of a certain good from one location to the other within a time limit. Travelling between places costs you money, so you need to make sure to make enough money along the way. The game takes place in real-time, and the hitman moves around the map in search of you. You can see his position and on the map, and you need make sure to keep your distance, as the hitman is also faster than you. The game takes the distances between places into account. Since there is no way to cancel a travel between two locations, the hitman can catch up with you if he's close to you.
