Untethered is a space survival-sandbox set in our own cosmic backyard. Explore zero-gravity environments, build and operate realistic space stations, and fight to stay alive in the unforgiving realm of deep space.

Stranded in deep space, you must survive against all odds. Scavenge from wreckage, process resources, and build your own space station - a refuge in the most hostile of environments.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/7a68fb12c8ebbcd146371a0bc7790ca1.poster.avif?t=1751006226" width=600 height=248 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/7a68fb12c8ebbcd146371a0bc7790ca1.webm?t=1751006226" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/7a68fb12c8ebbcd146371a0bc7790ca1.mp4?t=1751006226" type="video/mp4"></video>Using a modular construction system, build your very own space stations to house farms, labs, and material processing equipment.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/f863edc0a529e27f2f9365efffb0de2a.poster.avif?t=1751006226" width=600 height=248 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/f863edc0a529e27f2f9365efffb0de2a.webm?t=1751006226" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/f863edc0a529e27f2f9365efffb0de2a.mp4?t=1751006226" type="video/mp4"></video>Take the role of a flight engineer and keep your station's equipment running smoothly.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/b318b3226dcdacf3a1d7a159eed878b3.poster.avif?t=1751006226" width=600 height=248 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/b318b3226dcdacf3a1d7a159eed878b3.webm?t=1751006226" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3018760/extras/b318b3226dcdacf3a1d7a159eed878b3.mp4?t=1751006226" type="video/mp4"></video>Stranded in deep space means food and water isn't exactly easy to come by.
