About Quantum Void
Quantum Void is a retrofuturistic cosmic thriller about space and dimensional mysteries, with multiple endings. You play as an engineer for CSMO, a faceless space corporation. Two months into an expedition, a dimensional anomaly separates you and your small vessel from the fleet, sending you to the outer layers of an unknown stellar system. As faint residual signals emerge, you investigate whether they come from the rest of the fleet and seek a way to escape.
Explore the system
The game alternates between exploring on foot and navigating through space. You pilot a welding-tugship across the orbits, locate wrecked fleet vessels, board them and explore. Use your radio and computer to retrieve and interpret what you find as you investigate the anomaly.
The world is semi-open and structured in a Metroidvania fashion. You can explore environments thoroughly, and details may matter as you work toward your objectives. On foot, you can make use of each vessel’s systems, including its electrical grid, computer network, air vents, crew emails and chats.
Play your way
Quantum Void is playable on a flat screen or in VR, which is optional. It is optimized for Steam Deck and other handheld PCs, and supports Bhaptics.
