About Omega Mouse Zero
Omega Mouse Zero is a 2.5D platformer and shooter set in the expanding Omega-Verse, where you explore interconnected dimensions, fight enemies and uncover secrets. You play as Omega Mouse, a mouse who survived interdimensional travel and became the focus of experiments by the Cats In Black. The game includes 3–4 hours of play, and more than 100 enemies can appear on screen at once.
Shadow Cat and the Omega-Verse
Shadow Cat is a stray cat taken in by Clock Wise Cat, a professor at a hidden academy of magic and knowledge. Feared by his peers for his power, Shadow Cat studies the Omega-Verse: a theory that infinite universes exist, each with alternate versions of oneself. He communicates with other Shadow Cats, forms bonds with them and vows to unite with them.
As an adult, Shadow Cat leads the Cats In Black and works with Top Hat Rat Technology to build quantum computers for interdimensional travel. Attempts to transport organic life end in fatal tumors, until one mouse survives the journey and is named Omega Mouse. Top Hat Rat, who oversees Omega-Verse operations, wants to travel between dimensions to extract resources for his scarce universe. Shadow Cat comes to believe that somewhere in the Omega-Verse, Omega Mouse has reached its prime and may come seeking retribution for the Cats In Black's crimes against mice.
