Psychic World (サイキック・ワールド) is an platformaction video game. It was originally released in Japan for the MSX as Psycho World (サイコ・ワールド) in 1988, and was later released as Psychic World on the Sega Master System and Game Gear worldwide in 1991.

The game play was typical of the average 2D Platformer. Lucia ran from one stage to the other using her ESP booster to blast monstrous enemies while obtaining item pick-ups through them or by jumping on various ledges and platforms. The Booster had a gauge of how often certain items and abilities could be used, but that, as with her health, could be replenished through pick-up icons.

All her weapons were upgradeable by merely picking up the same item for that particular weapon and new weapons were obtained through mini-bosses and end-level bosses. The player had to use Lucia's psionic weapons strategically in levels using different elements to their advantage. In the ice stage, rocks being doused by falling water could be frozen and used as a stable platform for Lucia to jump on by blasting the rock with the ice shot, while the sonic wave weapon could destroy certain foreground objects blocking her path.
