Psichodelya is a vertical shoot-em-up (aka SHMUP) game set in futuristic environmet where two races of mechanized alien species are waging air warfare over Earth-like pieces of land. Player controls one of 3 playable ships, dodging heaps of bullets and killing wave after wave of enemies for points in single or 2 player local coop, over 5 levels culminating with epic bosses. Psichodelya is special because in this game player ship has a colored shied that protects from a numeber of bullets from the same color as the shield, and at the same time enemy ships are also color coded, making them more vulnerable to one type of damage.
