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

I love how immersive it is, the level of details is amazing.
Runs Perfect On My 166$ PC The Only Thing That Would Make It Better Is More Maps
This game live up to the expectation. Very stable coop, beautiful graphics, scary and challenging. It looks carefully crafted for an early access. I love the overall vibe the game has to offer. Most of the time you are forced to adapt depending of the entity you are facing and the purpose of the mission. This adds random which is nice, but there could be more special events, inreasing the difficulty in somes ways or tricky things to do overall. Has to offer : Character/ship customisation. Proximity chat. Friendly fire. Sets the mood. High risks high rewards. No stutter/frame drop/crash etc.. Lots of fun.

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.

Definitely a real horror experience. i find that most horror is too cliche or predicable. or i laugh at how hard it tries. but this game is full on horror and does not rely on jumpscares as much. great music and amazing ambience and atmosphere.

The game is good...If u can play?? but the community is toxic AF. People kicking you for... nothing? or i don't understand why? Anyway i just don't wanna figure what i did wrong. refound asked.
Great little coop game for a group of friends to jump into! Good environment design and sound and creativity all blend into one to create very atmospheric missions. Hard at this point to say how long the environments and ambiance will stay fresh for, but the game is terrific value at the current price point.
Jeu avec beaucoup de potentiel, mais beaucoup de problèmes. Déjà, vaut mieux avoir des amis pour le faire, c'est plus drôle. Le jeu est plutôt beau, mais terriblement rigide. La variété des missions est trop peu grande malgré certaines nouvelles mises à jour. L'IA des monstres est aléatoire en fonction des games et rend le tout frustrant. Le pire étant les collisions entre les alliés qui empêchent de courir dans les pires moments (et ça encore, c'est drôle parfois si tu te débrouilles pour que ton pote meure à ta place). L'ambiance des maps est en revanche bien travaillée et l'aspect détective Scooby-Doo pour savoir quel est le monstre est bien foutu. J'espère que de nouvelles mises à jour continueront, car le potentiel est là, mais n'est (pour le moment) pas bien exploité. 5/10
Great game at a great price
its fun!
