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 don't get it. People like this game? For me it breaks immersion with every turn: you have to collect bunch of the same cards to unlock doors? You have to collect money laying around to unlock upgrades? Then our first specimen (#8?) is some hillbilly rockstar with hair tentacles chasing us? Not immersive. It's too goofy to be scary. It just feels annoying. There's no eerie atmosphere like there is in Backrooms for example. Screenshots are fake, the game doesn't look that polished and runs poor for the actual level of fidelity. However it certainly has potential, but I think it has a long way to go still.
fun and scary however the "puzzles" (more-so fetch quests) to complete objectives consist of "walk around until u find out what ur meant to do" and that leads to some explorations taking 20 minutes longer than they should simply because u missed a single room in the corner - pay VERY close attention to ur minimap the monsters have real challenge and it always feels like youre teetering over the edge towards death good game 8/10

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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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.

Very cool game with lots of potential. Very clearly early access, but worth the price. I am very much looking forward to where this game goes.

很难想象四十块的游戏能有大工作室出品一两百块的质量,音乐氛围好场景更是顶级而且不吃配置,女号捏脸挺好看,难度的话像击杀还有收容或者带掉电闸词条一个人就很难完成了跟朋友组队就会体验好很多,新手需要背地图哈。目前在国内还挺冷门的没啥国人玩,期待出新地图新怪还有新装备
Probably the best horror co-op title I've played. The initial experience is very immersive and scary, and the game continues to make your heart race as you gain experience and take on more difficult contracts. There is decent player progression and various tools you can equip such as a force shield, entity tracker, etc. There are also some basic cosmetic options as well. The game is still relatively new, and the Devs seem to prioritize quality updates and delivering a well-tuned experience. It is a very pretty game that runs with very few bugs. There at least 15 hours in the core progression system (at this point), and decent replay value after, especially for those who want to complete their codex. With all of these qualities it punches well above it's $10 price tag. Great solo, but truly a blast going in blind with friends. If you're on the fence just try it!
great atmosphere for the horror genre lovers out there!
J'adore ce jeu, manque un peu de contenu mais il est en très bonne voie
