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.

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.

Buen juego. Definitivamente, es una experiencia distinta a todo lo que he jugado antes. Me he divertido bastante jugándolo con un amigo. No lo juego yo solo porque me da miedo, jajaja, pero con amigos es muy divertido. No tiene el reconocimiento que se merece, aunque también es cierto que aún está en acceso anticipado, por lo que todavía tiene mucho margen para crecer. Si los desarrolladores continúan añadiendo contenido y puliendo la experiencia, creo que podría convertirse en un gran juego dentro de su género. Si te gustan los juegos de terror cooperativos y descubrir cosas junto con tus amigos, definitivamente vale la pena darle una oportunidad.
very fun game with friends not friend slop it a blast everytime
Le jeu est très cool le seul soucis est qu'il y a une seule map pour l'insant !
Amazing game! It's in early access and it already has me hooked, can't wait to see more!
Vraiment sympa, dev en or, Speed run possible! un vrai plaisir a jouer solo ou avec ses amis c'est drole
A surprise hit for me that I would certainly recommend to my friends. I'm not certain what I like more: The idea that the monster is random every mission or if what loadouts you bring to the mission will be average or excel because of the niche situation the monster brings to the table. For instance, there is a monster that can poison you and the poison will kill you. Did your teammate bring a health injector to take care of you on the spot? If not, you are now running to the nearest health post but are you going the right direction? Are you map knowledgeable enough while under pressure to make it to the nearest one? Or do you have the mini-map tool that will potentially show where you need to run to get yourself healed before the poison kills you and makes your corpse another zombie for your team to fight? A solid 8 out of 10 and I just want more.
TLDR: There isn't a TON of content out for it right now, but what's there is great. Highly recommend, especially for the price and especially with friends. A lot of love when into this game and it really, REALLY shows.
Really fun, lots to do, good gameplay mechanics. Unfortunately the vents are really annoying if there is a species that can go in them.
