Every market we collect.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
About
Species: Unknown is a first-person survival horror game, playable in co-op with up to 4 players (private or public servers) or solo. You play as a mercenary sent aboard an abandoned spaceship. Your job? Execute high-risk contracts, make it out alive, and claim your reward. But keep in mind that you’re not alone. Something is hunting you…
Form a squad of up to 4 players to take on different contracts with escalating difficulty. Each mission plays differently depending on your objective, your teammates, the map and which of the 5 intelligent threats is stalking you. No one survives alone, but you can try.

Proximity Chat & Radio are available: distance matters, walls matter. Proximity Chat is bringing more tension, sometimes chaos, and unforgettable moments to your co-op sessions.

Every contract drops you into a different nightmare. Whether you're tasked with extracting a black box, capturing or eliminating an unknown threat, or even destroying the ship to prevent the creature from escaping… Each mission demands a specific strategy and none of them are easy.
The specimen is chosen procedurally from a growing roster of terrifying monsters. Each one comes with distinct behaviors, hunting patterns, strengths, and weaknesses. You’ll need to investigate your surroundings to gather vital clues and identify the threat in order to proceed smoothly (or not). Do your job and get rewarded, or die without anyone knowing.

Strategize as a group, make smart use of your tools that can turn the tide, if only for a moment:
Motion Tracker : Detect nearby movement and prepare for what's coming
Shield : Block deadly attacks and buy time for your team
Health Syringe : Heal yourself or allies in the heat of battle
Mini-Map : Navigate pitch-black corridors with real-time positional data
Guns won’t always save you. Some threats are too resistant or simply untouchable. But the right weapon, found at the right time, can help you push through or even take the creature down.

The higher the risk, the higher the reward. Completing contracts earns you credits you can use to:
Upgrade your gear
Buy new tools
Customize your appearance
Gather lore and build your own creature museum

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
Reviews, worldwide (the counter carries no country): 18.86/day in the week to Jul 31 → 19.57/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,420 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Lethal Company meets Alien Isolation maybe? It's a bit of a sleeper; I hadn't heard anything about it until I saw a reel for it on Insta. Pleasantly surprised at how fleshed out it feels compared to something like No Backup. Currently there is only a single map, but it's large and detailed. There are a good number of species to get to know (6 currently, I believe). Game can be played with up to four others, but it's completely playable solo as well, even up to the highest difficulties. The gameplay relies far more on memory (locations, species behaviour, etc.) than skill expression, so people of most skill levels should be able to enjoy it. It is important to note that the game rewards patience, and the slow crawl through the map might not be for everyone. You can technically sprint through the map if you like, but this will often lead to more aggressive pursuit by the resident specimen. Can't wait to see the upcoming additions as this game makes its way through early access!
super fun highly recomend
the player base are crybabies that abuse the kick system that the game has for no reason well there reason cause i sound different in a video game and i don't sound like someone they want me to sound like you are there child and I'm no else child besides the one that birth me and they can keep this ♥♥♥♥♥♥ game with the weakest play back loop i have ever seen the game is more boring then anything and no it doesn't have to be in your face dead space scary. but if you are trying to capture that then lean hard on the scares not paper flying up trying to pennywise you. This game is fun on the surface, but the more you play the more un fun it feels wrong. but that is rarely the case in this game. The game incentivizes your team to have a single person kite the enemy in a circle while the rest of the team tries to complete the objective, which is not fun. I want to like this game, runs great, looks amazing, but it's just SO frustrating
yeag
Its a good game, though updates are very slow. While the same map can get kind of boring, all the specimens are pretty fun to play against, so still worth it.
Very fun with friends. Love the screaming. The game made Ghosty rage so I give it a 10/10.
I find this game very fun, both with friends and alone
