Planet Laika (プラネットライカ) is a role-playing video game developed by Quintet and Zeque for the PlayStation home game console. The game follows the main character, Laika, through a mission to Mars which forces the player to manipulate Laika's multiple-personality disorder in order to solve puzzles. All the characters in the game have dog heads, a possible reference to the Soviet space dog Laika. The game was only released in Japan.
Unlike most RPGs, which feature turn-based battles, Planet Laika's are played out almost like Space Invaders and Pong. The player must bounce around a Mind Core and reflect back the enemies' attacks to inflict damage. There are not a lot of battles in the game and enemies only attack when Laika is in one of the special forms.
The Evil Mind starts affecting the space crew including Laika himself. The first one who got heavy side effect of the fog is Noon as shown from his panicking tone and body movement followed by hallucination of his dangerous mother coming back while Tatler suddenly changed into an easily irritated and ignorant man due to the fog's effect. The one who doesn't seem to be affected here is April. This is not good because after April and Laika return, the safe house's door is opened and both Tatler and Noon are gone. As April went ahead to the town to look for them, a cloud of sand dust suddenly fly closer to Laika and a boy in a digging suit emerges from the Mars ground. This boy is Damian and he tells Laika that his friends, Noon and Tatler gone ahead following their hallucination from The Evil Mind's effect.
Upon arriving at Brick Road, a drunken sick purple-skinned man named Sammy comes out after giving up to open the mysterious door beside the eye symbol. When Sammy returns to the town, Laika absorbs a large amount of red aura from him which changes Laika's mind scope's color into red with an unfamiliar face replacing Laika's face in his mind scope. The Spirit Man appears and tells Laika to follow him into the mirror room. Now, this is where the gameplay concept begins...
On Mars, every character has their specific aura color (The colors are red, blue, and yellow or green. Red aura came from a person of Animal type with lust for power and violence, blue aura came from a person of Psycho type with lust for knowledge, yellow or green aura came from a person of Visual type with lust for beauty) and talking to one of them will make Laika absorbs the aura from the person he is talking to. If enough specific color is absorbed, his mind scope will start turning color based on the dominant color and a different face appear instead of him. This face is his other personality from the DID and each of them will be called after Laika look at himself in any mirror to solve the puzzles later (Ernest as Animal type, Spacer as Psycho type, Yolanda as Visual type).
For the first introduction, Laika changed into the Animal type personality named Ernest
