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

This game is really fun with friends! I'm excited to see what new maps come out and what other species are introduced into the game! People have to remember that this game is still early access, and we've let games be out longer in early access and have had barely any real new updates (ahem, 7 Days to Die), so I'm willing to give this more time to let it flourish and become more whole of a game. But so far, I'm really enjoying it. To the negative reviews, perhaps get more friends to play with? One criticism, I do agree that the AI can be a bit wonky at times, for example, the Ghost has a bad habit of getting "stuck" against walls sometimes after being fought and then fleeing - a friend of mine says the Ghost isn't the only that has this problem. Also, even on lower levels, the AI can be super aggressive as if it's on level 4, which is insane. It needs some adjusting. But, I'm willing to give the devs grace to work that out. Final note: 010 is the cutest monster.

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 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.

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.
A very fun and challenging co-op game. Graphics are really good and was well optimized for me. Looking forward for a new map.
Ну хз каким надо быть говноедом чтобы нравилось в это играть, да контент есть(88 миссий однотипных "принеси" "выключи" "перезапусти" "перни" "подрочи")Сердобольно чуть чуть прокачечки с барского плеча за внутриигровые денюшке) и то как я понял на один сейв чисто. Есть разное вооружение, но это юзлес говно ♥♥♥♥♥♥♥))) Ожидал что-то другое, восторженные отзывы игроков и скидка сподвигли на приобретение данного продукта. По факту - дерьмо из жопы, те кто крутят пальцы вверх этой игре, дегенераты и имбецилы, это супер средняк и супер проходняк. Игра сравнима с квотагеймингом, только там за такой-же ценник получаешь много эмоций в коопе, хоть и не надолго хватает в основном таких игр. Тут спустя час мы начали ффашиться(из оружия нельзя убить местных тварей, но зато можно убить очень даже не местных кентов) и дружно нажали альт+ф4. Игра ♥♥♥♥♥ и говно
where is the update?
needs more blow job objectives
The value of this game for only $10 is crazy. Any AAA studio would be charging you $40+ for it and people would eat it up. The audio pulls you in and gets you right into that eerie feeling of unease. The lowlight visuals bring to life the horror around every corner. I cant wait to see the future of what they do for this game and the new areas theyll take you to, along with the new species the bring in to hunt and kill you. I wish they would add the ability to lean, jump/vault and ping. For $10 i cant recommend this game enough if you like the horror/suspense FPS with a team objective.
Игра просто космос! Настоящий глоток свежего воздуха после всех игры про охоту на призраков! Первое что бросается в глаза - это качество, игра ощущается как действительно качественная АА проект, причем чуть ли не с самого меню. А еще какой простор для развития, сюда столько всего можно добавить ух! В общем игра просто огонь!
