# COSMONAUT Summer DB entity ID: 607fd7e0\-b43c\-41bf\-b428\-ebc46878051b Steam App ID: 743550 COSMONAUT is an immersive story\-driven horror platformer set two centuries in our future\. Suit up as Jarobi, a green DSR \(deep space reconnaissance\) contractor tasked with boarding the S\-class research vessel, Diogenes\. Lost 80 years prior in the vast Kuiper Belt, the vessel has become an iconic symbol of humanity's early manned voyages to the outer solar system\. The ship is for the taking, but at what cost? Creatively explore a decrepit futuristic environment via unique movement mechanics, free from gravity using any surface you choose\. Survive the dangers of deep space habitation through various puzzles and challenges\. Arm yourself and choose to merely defend against, or fully exterminate foes of both extraterrestrial and artificial origin\. Put your psychological resolve to the test and become the first to unravel the mysteries surrounding the lost Diogenes vessel\. ## Game information - Type: game - Developer: Neon Chasm, LLC - Publisher: Neon Chasm, LLC - Release date: Jan 11, 2018 - Coming soon: false - Free to play: true - Parent Steam app: Not collected - Genres: Action, Adventure, Indie - Categories: Single\-player, Full controller support, Family Sharing - Platforms: windows - Website: Not collected - Screenshots: https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_48ec71d852cb0ec48e75c31c66c4e2872fdbc3e4\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_370688263ba831efeb2ecfdbdcfe9d89919b3532\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_816cfd5f634f4523e359352b1334d2faf6418157\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_f13cd04f4e9dfcbcf08ee5e7e1bf6172cf5fae59\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_1587054d5972672aa948eaefc20ec9a4f3c425fa\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_c5f64a812d7f1fc3bcc0e054ae438cd6029149ba\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_2b567f8f04b2748da4592f3601dc779e8f32849b\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_47e3c2b923040f01c85b3b49a4c8d5edc118db3f\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_9dfa9381a1b891c49e20c20edb01b6369050a0be\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_f9f8047db273f9ad298c45fd948f2b4b177b6e55\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_a7d0db849aaf95b6144f6b6f8f94c5d1f6208cd3\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_b3baaae85c5aaf403762958eaae26ebd391347f4\.1920x1080\.jpg?t=1577823716, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/743550/ss\_77919163adf45a241aea7eaac2551ea136c4b2c9\.1920x1080\.jpg?t=1577823716 - Price: Not collected - Price country: Not collected ## Observed metrics - Current players: 0 - Steam review count: 44 - Steam positive reviews: 38 - Steam negative reviews: 6 - Steam positive percentage: 86.36363636363636% - Summer DB rating: No native votes Review filters: \{"language":"all","review\_type":"all","purchase\_type":"all","filter\_offtopic\_activity":0\} ## Player history [Seven-day chart data as Markdown](/api/v1/entities/607fd7e0-b43c-41bf-b428-ebc46878051b/player-metrics?days=7&format=markdown) · [JSON](/api/v1/entities/607fd7e0-b43c-41bf-b428-ebc46878051b/player-metrics?days=7) Chart values are hourly observed maxima.
