Doomsday Warrior

Doomsday Warrior

Doomsday Warrior is an action-adventure game where a member of the Doom Squad has resisted the influence of an evil sorcerer and now must fight him before he takes over Earth. It was originally published in 1992 for the Super Nintendo Entertainment System, and players must defeat corrupted members of the Doom Squad, as well as three bosses in order to save the day.

Fire 'N Ice

Fire 'N Ice, aka Solomon's Key 2, is a prequel to Solomon's Key that was originally released for the Nintendo Entertainment System in 1992. This puzzle game is framed as a story being told by a grandmother to her grandchildren, which works for its fairytale-esque gameplay.

Players will control Dana, who has been chosen by the Queen of Winter Fairies to defend Coolmint Island. To do so, Dana must use his new ice magic against the evil Wizard Druidle, whose main power source is fire. To save his home, Dana must put out all the fire monsters scattered through over 100 levels, gaining abilities and structural assistance as he goes.

Prehistorik Man

Prehistorik Man

Prehistorik Man is a sequel to Prehistorik 2 originally published for the Super Nintendo Entertainment System in 1995. It's a side-scrolling platformer with a rich story and NPCs who will provide hints for players as they move through each of its 23 levels.

Players control Sam, a young, agile villager living in the Stone Age whose chief has tasked him with finding food so they can survive the winter after a group of dinosaurs steal their stores in the night. To accomplish his task, Sam must find bones, which he can trade for food.

Psycho Dream

Psycho Dream

Psycho Dream is a psychedelic action game originally released for the Super Nintendo Entertainment System in 1992. After a teenage girl named Sayaka disappears into the immersive world of a D-Movie and has just hours left to live, two debuggers named Ryō and Maria are dispatched to rescue her before she dies.

Players can choose to control Ryō, a swordsman, or Maria, an angelic warrior. The latter has a whip that can later be upgraded into metal claws or a gun; she can also summon demons. Since Sayaka is on a time crunch, so is the player -- the goal of Psycho Dream is to progress through each level as fast as possible.
