About the Game
The Swap Mechanic and Realistic Physics System
Central to Bionic Bay is an innovative swap mechanic and a realistic physics system. When combined, these offer a new way of interacting with the environment – from shifting gravity to interchanging positions with objects and adversaries, and to move, defend, or attack. But be careful not to burn, break, freeze, explode, or vaporize in the process.
An Ancient Biomechanical World
Plunge into an ancient, biomechanical world teeming with imaginative devices, mysterious technology, and peculiar inhabitants. Get lost in the vast sci-fi landscapes in gritty high-density pixel art style and suspenseful sound design that makes each biome distinct. Attempt to uncover the secrets of the ancient world.
Platforming Built for Speedrunning
Fluid movement and reactive physics make for high adrenaline and action-packed moments in each uniquely designed level. Creatively navigate around the many curious hazards by precisely executing the right combination of swaps and maneuvers. And perhaps… have a go at completing each level as fast as you can.
Online Mode: Competitive Speedrunning, Leaderboards, and Character Customization
Test your mastery in timed races against other players’ ghosts and leave them in the dust to claim the top spot on the leaderboards. Stay stylish while trying and recognizable on the boards using the in-game feature that lets you create your very own scientist. And through it all, remember not to rest on your laurels, as the Online Mode updates with new events regularly.
