Planet Laika is a role-playing game where the player controls Laika, part of an expedition to Mars, searching for truth about rumors surrounding the end of the world and a supernatural creature. The goal is to uncover what's real and what's not.
The game features multiple-personality disorder for Laika, with different personalities manifesting as colors in the aura around characters: yellow for physical beauty, red for strength and violence, and blue for psychosis and cunning.
Laika can absorb these auras, taking on different personalities by filling a gauge and using a mirror to transform. These transformations help solve puzzles, like becoming "red" to lift heavy objects.
The battle system is similar to Pong, with the player deflecting enemy projectiles to inflict damage using a Mind Core. Battles only occur when Laika is transformed into an alter ego. Like many RPGs of its time, Planet Laika uses 3D polygonal characters and 2D pre-rendered backgrounds, along with CG cutscenes.
Planet Laika was released on the PlayStation in October 1999.
