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.

le robot avec la berline est un gros batard
On voit beaucoup fleurir ce genre de jeux en ce moment, façon lethal, repo etc... Un principe simple, bête comme tout, mais efficace. La grosse différence ici c'est que contrairement aux autres on est sur un jeu visuellement très beau, et donc avec un réalisme qui nous plonge davantage dans cet univers mis en place et donne aux parties des enjeux "plus sérieux" et prenants. Bref, c'est une super découverte, toujours un plaisir de le lancer. Evidemment plus fun avec des copains mais pas infaisable en solo. Une difficulté bien dosée, un bestiaire diversifié et un jeu qui a le mérite d'être mis à jour assez régulièrement. Bref une belle découverte !

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

I can see the vision, and it's good. I anticipate this being a solid title further along when there's more content. This is a pretty well polished experience for you and your friends, and is worthwhile right now for its current pricing.
Awesome game! Can't wait for more content and the full release!
This game has completely blown me away. I picked it up expecting to play for a few hours, and before I knew it, I had spent 14 hours in a single day with only a few breaks. I haven't been this hooked on a game in years. What makes it stand out is the potential. The developers are actively listening to the community, pushing updates, improving features, and showing that they genuinely care about the future of the game. That's something you don't see often anymore. If they keep this momentum going, I honestly believe this game has a real chance to become one of the top-rated titles among both casual players and streamers. The gameplay is fun, the progression feels rewarding, and every session leaves me wanting to jump back in for more. Don't just take my word for it, give it a try and see for yourself. I rarely leave reviews, but this game impressed me enough that I felt it deserved one. The future looks incredibly bright, and I can't wait to see where the developers take it next.
This game, for 10$ is one of the best values you'll ever get. Please keep this going Devs.
