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

underrated game
Game is very cheap and less than 5GB. Price and download size aside it is still one of the games of all time, super fun horror style missions with Jarvis and his alternate half Pornvis. Love where the game is headed and I am excited to see where it ends up when it leaves early access. Who/Me for this game. Thank you developers for making this.

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
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.

Très bon jeu à faire avec des potes. Si je peux donner quelques idées, Pour la mise à jour d'octobre, le fait qu'il y ait tel spécimen sur tel map pour nous obliger à changer de map. (sans nous l'indiquer, on pourra le découvrir en jouant). D'avoir un spécimen plus axé sur le fait de se cacher et sur la peur de le rencontrer comme si c'était un cauchemar éveillé (peut-être faire en sorte de pouvoir se caché sous des tables, dans des casiers) et qu'il s'adapte un peu comme l'alien dans alien isolation plus tu te caches au même endroit plus il y a des chances qu'il te crame. Mais toujours pour ce spécimen, cet mécanique ne doit pas gâcher les autres rencontres avec les spécimens déjà en jeu. Les autres spécimens pourraient en avoir rien à faire que tu sois caché ou non. N'hésitez pas à me dire en quoi mes idées sont bonnes où mauvaises! :)
맵 하나밖에 없는거 빼고는 그래픽도 좋고 재밌네요 이대로 맵 하나만 내고 끝나면 아쉽겠지만 지금 상태로도 가격대비 살만하다 생각합니다 파스모포비아 재밌게 했고 SF 좋아하면 추천
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.
Beware! This game is HIGHLY UNFAIR and BARELY PLAYABLE IN SINGLE-PLAYER mode! If you plan to play solo - don't buy this or you gonna regret that as I did! I've played this for 13 hours and thus not suitable for refund, but I highly regret that I bought this game! It's a pity, 'cause this game has a pretty intertesting concept and setting. 2/10 for single-player. Dev's - you shouldn't made this game single at all it's concept works only for coop! PS. This studio also created "Propagation VR" - an absolute gem for VR horror-shooters. I bought this because of that, hoping that their next game would be good as the other, but, alas, I was mistaken. This is sad.
where is the update?
Yes. Incredible game so far. Surprised its not talked about more.
Genuinely fantastic game. For an early access title and from a small studio the game just oozes atmosphere and the team have done a fantastic job on nailing that feeling of space horror. Only just started but i'm hooked already. Huge customization, runs brilliantly and looks stunning for a small game. Roadmap looks solid as well and excited for the new map in October (2026). The tools and weapons are fun to use as well. Really pleased i've discovered it and with coop buddies it's a blast. Solo is a whole different experience that can have your palms sweating at times. Genuinely loving what is here. If you're a fan of sci-fi horror then you owe it to yourself to check this one out.
really fun to play
