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.

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

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.

super excellent game wallah super beautiful too i love it 100%%%%
The game plays very well, sure right now there is one map and a handfull of monsters but trust me you want to play as much time as you can to learn the map. As each monster changes how you work each map on top of the map mission type and modifiers. My only beef would be how scripted the monster feels after you encounter it a few times. It feels so fake when so much detail has gone into the game. For example the scorpion/virus/zombie monster claims to be afraid of fire but it will walk right next/through fire unless you have the canister right under it when it goes off. Very noticible and frustrating it's activly humting you. I can understand if the ships about to blow up that a monsters behaviour is going to override the discription/behaviour but when I've "extracted the data" and the agression level jumps up a level or two that it hunts you even if there are body's in the area it can use, makes me go WTF? Would love to see the Monster act more natural/logical, like it makes "smelling" noises if the design is for it to lurk in the area a player is in. For there to be more things, like objects you can knock over that can make noise in the area. Doors you can lock, not juse unlock. Forcing the monster (or players accedentaly) to go the long way or through a a vent. For some "interactions" have the ship do a broadcast letting team mates/monster know what's going on. As not every game every player is being sociible. Last I've seen the monster jump from one side of the ship to the other say when another player is looking for creds/wepons/laying traps. When it's hunting or being observed it doesn't move that fast to make it possible. That lack of realisum when again so much detail went into trying to immerse the player, does the dev's that made the map a disgrace.

pros:immerse - fair optimization - creative species - enjoyable co-op experience cont:1 map - repetative - lack of rng - upgrades are basic and easy to max out, there are no long term grind goals - no scaling for solo or 4 player co-op or if there any scale then it's kinda bad multiplier.
игра прикольная , жуткая, лично я хотел-бы увидеть в это игре броню .Броню разных размеров, прочности веса, в плане если ты оденешь лёгкую броню то скорость будет сниже допустим на 3% а если тяжёлую то будет снижена допустим на 20% при этом лёгкая броня она будет снижать получаемый урон на 2-5% а тяжёлая будет снижать получаемы урон на 30% ! и это брони будут иметь разный визуал и лёгкая броня, средняя броня, увесистая броня и тяжёлая
The game is absolutely Phenominal. I cannot wait for a new map. The enemies are scary, the atmosphere is amazing, the performance is so smooth. I wish AAA Devs would make games this good.
the game is good but after a while it gets repettative
