Psychic World is a Sega Game Gear action platform game developed by Sanritsu and published by Sega in early 1991. Like its Master System counterpart, it is a port of Hertz's 1988 MSX game Psycho World with notably fewer levels. Unlike the Master System version, it was released in Japan and the United States. During development, it was titled Psycho World in Japan, the same as the original[10].

The Game Gear version has redesigned graphics and levels from the Master System version. Despite the smaller screen size of the Game Gear, the playable area is nearly the same height as the Master System game because of the large HUD in that version.


Psychic World GG, Lucia.png


Dr. Knavik, a research scientist doing experiments with animals, hired the twin sisters Cecile and Lucia to work as his assistants. One evening, when Dr. Knavik and Cecile were working late and Lucia had gone to bed, an explosion burst from the lab. Lucia rushed to the lab to find that Cecile had been taken by the animals. Lucia asks Dr. Knavik how she can get Cecile back, and Dr. Knavik gives her the ESP Booster, a special helmet he developed that gives her psychic powers.


Psychic World is an action platform game. Players control Lucia through a supernatural world as she pursues the monster abducting her sister. Each round presents numerous platforming challenges, a mini-boss partway through, and a boss at the end. Lucia can be moved with Left and Right; holding either button causes her to run after a few seconds. She can jump with 2 and crouch with Down. She enters doorways with Up. She climbs ladders with Up and descends them with Down. She can switch to a standing pose on a ladder with Left or Right so she can fire her weapon.

Lucia has a projectile weapon that she fires with 1. She can fire while crouching or jumping. Lucia starts the game with a Psy Cannon and obtains new weapons by defeating bosses. Her weapon is weak at first but can be upgraded over the course of the game. Some weapons are more effective against certain enemies, and some grant Lucia special abilities such as the ability to freeze water into ice blocks to create platforms.

Lucia also has four special ESP abilities that grant her special powers such as temporary invulnerability or levitation. Unlike her weapons, which are unlimited, these abilities cost ESP when they are used. Lucia's ESP can be restored by items and is also fully replenished every 1,000 points earned by the player. The rounds are designed so the player must use Lucia's various weapons and abilities to overcome specific challenges.

Psychic World GG, ESP Window.png

The player can change Lucia's weapon or use an ESP ability at any point by holding 2 and pressing Down, which pauses the game and replaces the HUD at the bottom of the screen with an ESP Window. The player can scroll the icons in the ESP Window with Left and Right and release 2 when the desired weapon or ability is selected. Weapons and abilities are upgraded by finding and collecting their icons, which are dropped by defeated enemies, throughout the game.

Lucia's hit points are shown in the bottom-right corner of the screen. Her hit points decrease when she takes damage from enemies and hazards and can be replenished by finding items or using the Shield ability. Unlike most platform games, Lucia does not receive temporary invulnerability when she takes damage (though she is knocked back if there is room), so it is possible to take a large amount of damage from a single foe if the player is not careful. If Lucia loses all of her life, she dies and the game ends, but it can be continued any number of times from the beginning of the current round. The player's score is reset, but items and upgrade levels are retained.

ESP Capabilities

Psychic World GG, Items.png
Activates a temporary shield that renders Lucia invulnerable initially and then drains ESP instead of health for the rest of its duration. Lucia can still be knocked back by enemies while invulnerable. If used again while the shield is active, it heals Lucia for a small amount. It can be used repeatedly to fully restore Lucia's health if the player has enough ESP.

In addition to these items, all of Lucia's weapons and ESP abilities can be found as item pick-ups. If she does not already have the weapon or ability, the item gives it to her. If she already has the weapon or ability, the item upgrades it for her (with the exception of Teleportation, which does not have any upgrades).
