Ecco Jr.

"Echo the Dolphin" compatible with 3D stereoscopic vision It has become easier to play with a new mode that eases the difficulty and a save function in the middle.

At the dawn of the 30th Century, dolphins and humans had been together in a cross-species society for 500 years. Together, they had set out to explore space, offering peace and friendship to all who would welcome it. But space had its dangers; a violent species known as the Foe decided to conquer Earth. However, the dolphins and humans drove them to the brink of defeat, and so the Foe sought vengeance on Earth. The few caretaker dolphins who had been left behind on Earth were not entirely defenseless; they were protected by their creation called the Guardian—a gigantic, sentient being made of a crystalline substance which projected a forcefield over the entire planet. Undeterred, the Foe made suicide attacks on the field, searching for a weak point.

Tasty Blue is an underwater side-scrolling eat 'em up game. You start as a small goldfish with an insatiable appetite. After being overfed by your owner, you'll escape into the ocean and eat everything that you encounter. The more you eat, the bigger you get! In addition to the goldfish, you'll also play as a dolphin and a shark. The dolphin starts off as an overworked aquarium star, forced to jump through flaming hoops for food. He escapes from captivity by eating his way through the aquarium and taking revenge on his trainer. The shark is the final playable character, an artificial fish created by scientists to save Earth's oceans. It uses self-replicating nano technology to consume everything in its path and convert their matter into its own. There's no telling how big this shark will get. There are over 50 levels in the main story mode of the game. There are also 15 more challenging bonus levels to play after the main game has been completed. There are three main environments to explore in the game: temperate, tropical, and arctic. There are a wide range of difficulty levels to choose from. On the easiest difficulty enemies do virtually no damage. On the most challenging difficulty enemies will eat you and cause instant level failure. Two players can play side by side on the same computer. Options allow for split screen (horizontal or vertical) or shared screen (this provides more screen space but constrains the movement of players together).

Ristar is a platform game developed and published by Sega for the Sega Genesis in 1995. A Sega Game Gear game, of the same name and genre, Ristar, was also released, which shared similar themes while possessing different level design and gameplay mechanics. The game stars an anthropomorphic cartoon star who uses his hands and long, stretchable arms to both move and combat enemies. Reception for the game has been generally positive, but the game's initial release was overshadowed due to the imminent ending of the Genesis's lifecycle and the succession of the Sega Saturn and other fifth generation video game consoles. While never receiving any sequels, Sega has re-released the game a number of times digitally and on Sega-themed compilations, and has occasionally given Ristar himself cameos in other Sega properties.

Primal tells the story of Jennifer Tate, a 21-year-old woman searching for her boyfriend through a series of demonic realms. As the story develops, more is revealed about Jen's past and her relationship with her boyfriend, as well as the nature of the demon worlds. In Primal, the player can control either Jen or Scree as they navigate the realms of Oblivion. As the game progresses, newer demonic forms are obtained, which prove invaluable in solving various puzzles and combat. Control can be switched between Jen and Scree at any time in game. When in control of one, the other will be operated by AI, performing various functions depending on the situation. During play, the characters can interact with one another, performing actions such as asking questions, or siphoning energy. When in control of Jen, the player may transform into one of four demonic forms for various purposes, depending on the situation (provided the forms are unlocked). When in a demon form, Jen experiences a boost in attack, defense, speed, attack range and access to abilities unavailable in a human form. The tattoo on Jen's back also glows when in a demon form, corresponding to various forms. Defeating enemies involves weakening enemies to the point where their hit points reach zero, at which time a finishing move must be performed to kill the enemy. While the moves differ in style and time taken, the final effect remains the same. Enemies can be finished off before the health bar reaches zero, and doing so leaves more residual energy. While Jen can remain in a demonic form indefinitely, taking damage will reduce health. However, hit points here are represented by demonic energy. When an enemy is killed, the remaining energy can be drained through use of Scree, who can store the energy for when it is needed. Jen can then call on the energy, siphoning it off to replenish her own. Scree can store a vast amount of energy, but also has limits as to how much. When in control of Scree, the player is invulnerable; Scree, being a gargoyle, cannot suffer damage, making him an effective scout. Scree is capable of climbing on stone walls, a necessary ability when traversing the realms. Scree can also store drained energy from dead enemies, which can be used to replenish Jen's demonic health, though he must remain immobile when doing so. Scree is revealed to be the long-lost Abdizur, who disappeared following an encounter with the lord of Chaos. In Solus, for a temporary amount of time, the player possesses a life-size statue of Abdizur via Scree, to combat Belhazur when Jen's powers are not fit to do so. The player may also possess other statues in an area under given circumstances. The player may also happen across various energy crystals, which can be stored and used if Scree's energy reserves are not enough and the player is at low health. These crystals are kept throughout the game, the only exclusion being when revisiting previous scenes, at which point they are reduced to a default amount. This means that the crystals function as extra lives, to a degree. If Jen is in human form, her health replenishes automatically if she is not in battle (human form only; demon energy must be replenished by either drawing on Scree's reserve energy or, failing that, by using a crystal). While in human form, Jen's health represents her presence in the demon world. If she loses all her health while in human form, she is returned to the human world, where she is in a near-death state. When this happens, the player must direct Scree to the nearest rift gate within a time limit (not seen on screen, though the voice of Arella warns the player that time is running out). If Scree does not reach a rift gate in time, Jen dies, and the game is over. Throughout the game, constant saving can prove onerous, particularly if the player wishes to backtrack and revisit certain areas. Provided a save game is present, the player may do so, and can revisit nearly all of the locations, once they have been unlocked via an in-game cutscene.

During the first global biowar, a powerful retrovirus filled the planet Avaron with new and deadly forms of life. Only a few survivors remain in O.P. Odysseus, an orbiting platform circling Avaron. Hundreds of years after the biowar, conditions on Avaron are still hostile but livable.
