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.

Very Good Game: While it can be called "freindslop" This is a very fun action packed yet scary game where every threat feels and plays different. At first the game feels very challenging and scary but as you upgrade and play more it becomes more fun to play while still having its tense scenes. When you get to high level contracts and have a really good squad you get what feels like level 10 Helldivers missions where despite little no communication the whole team works together and helps one another to tackle the threat. Can't wait for more things to be added highly recommend this game. My 1 complaint is I wish there was a way to text in game as someone with a bad mic/mute.
es el mejor juego de terror con tematica espacial que eh jugado me encanta la referencia a las peliculas de alien por como esta hecho la ventilacion estaria bueno ver a un xenomorfo otra cosa que estaria bueno es que le pongan una dificultad en donde se pueda enfrentar a DOS especímenes al mismo tiempo eso seria genial y la verdad el juego da como para que sea de a CINCO jugadores aun que sea solo para CUATRO seria good uno mas, el juego es un 10/10 RECOMENDADO

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 2,515 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.

Excellent co-op horror. The devs keep adding content and the sky's the limit with these guys. It is already really fun to play either solo or with friends, and the potential is immense.
Jogão!!! Muito bom jogar co-op com os amigos !! Sustos, risadas e muita tensão no game. Observações no jogo: nunca aceite um contrato sem saber qual é a espécie que vai enfrentar kkkk... Gostei muito do jogo xD..
