About this game
A toxic gas is spreading across the world, poisoning everything in its path. While everyone else succumbs, you are the only one immune — and the last hope to stop the organization behind this threat.
This is an action-packed roguelike/metroidvania, featuring handcrafted, interconnected maps that create a seamless journey of exploration and discovery. Each biome presents unique challenges, enemies, and powerful bosses that will put your reflexes and strategy to the test.
Along the way, you’ll be able to choose permanent upgrades that shape the style of your run, allowing you to evolve your abilities and adapt to the dangers ahead.
With its retrowave and cyberpunk aesthetic, the game delivers frantic combat, a dark atmosphere, and rewarding progression in a desperate fight against the collapse of a poisoned world.
Are you ready to face the gas?
