Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
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
Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

Erken erişim için güzel, ♥♥♥ repetetive ama simdilik 10 saatten daha fazla oynatmaz bence
Firstly, I just gotta say... this game is absolutely amazing. like 6/5 stars I swear. The game is so much fun, the graphics are great and when you really get into the gameplay... the game is so incredbly fun. The best part is that this game was just 10 dollars. I cannot believe this game was that cheap. I HIGHLY recommend this game. It is so much fun with other player... especially with friends and meeting others in the game.

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 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.

We really do enjoy this game, we hope for more content. More maps would be nice. And we would like the plush of the little octopuss to stay in the ship when we return from a mission.

this game looks so good oml
From what I've played, it's a VERY well-produced take on an Alien-style horror co-op. Whoever made this was a big fan of that series, and they captured the essence well! Much higher production value than I was expecting, and the escape sequence mechanics were very well thought out and engaging! Not much else to say, just genuinely impressed, even if it's something I would only really play with friends who are ready to lock in.
Je mets l'avis négatif jusqu'à qu'on arrive à évacuer en mode facile avec "010". On arrive à la navette, il est juste derrière nous, il rentre, donc on ressort, on manque d'endurance et les 200 zombies nous bloquent donc on meurt, on revient et même chose jusqu'à la limite de réapparition. Les armes ? Oui, mais quand une énorme bestiole te court après tu peux pas prendre le temps de shoot les zombies. C'était le mode facile et on était 2, je pense que c'était pas super bien équilibré.
Actually a CRAZY game for the price, its so good, fun,not too grindy and the ONLY thing that i dont like is that there is one map. Please devs, add new maps or maybe make the current HSS hawking bigger. get this game.
