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.

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

Bueno, en mi humilde reseña, es un JUEGASO. suma muchos puntos si lo jugas con amigos, es muy inmersivo, y te pegas unos buenos sustos. Hay algunos bichos que asustan mas que otros, algunos tienen potencial (mejoren al de los zombies) El pulpito es tiernito. El mutante raro esta bueno en concepto. El bicho de las polillas es letal, pero si miras el piso safas. Creo que el MEJOR SIN DUDAS es el TERMINATOR, si te descuidas te culea, suele separar a los equipos, si vas sin mini mapa es mas dificil. En un grupo esta bueno que uno use el mini mapa, y otro use el detector de bichos, te da mas juego. Para los que se aburren de que es el mismo mapa siempre, soy un gordo ligoleyen, juego el mismo mapa hace mas de diez años, y no aburre. Metan mas bichos, es por ahí, háganlo mas de terror, que es divertido. Juegazo, compra campeón, compra. SALUTEEEEE

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 2,400 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.

This game really has huge potential. It certainly hasn’t reinvented the wheel, but it’s definitely given it a fresh polish. The game combines horror with a whole lot of fun – but only provided you have at least one friend to play it with (imo). The graphics are good, the sound is good, the game is good. Of course, it’s not perfect. After 20 to 30 hours (depending on how much you trust your skills and whether that turns out to be justified in the end), you’ll have achieved everything there is to achieve. There isn’t really any long-term investment of your in-game currency. There are perks and a shop, but you’ll quickly max them out. That doesn’t mean it stops being fun, though. The shop, the perks and the map provide a really solid foundation. Of course, you’d like to see more species and a new map – more variety overall. But the developers have already announced that more is on the way. For a small studio, it’s a really brilliant game with plenty of untapped potential. So if you’ve got €10 and 1–3 friends, it’s a good investment.

It’s four blokes trapped in a pitch-black starship, hunting a procedural monster before it eats their faces. The clever bit? You can't just shoot it. You have to scan logs and play detective to figure out what it is first. The atmosphere is brilliant, the proximity chat is terrifying, and when your mate accidentally locks you in a corridor with a murder-alien, it’s proper comedy. It needs more maps, but as a cheap co-op horror? It’s... the most fun you can have dying in the dark.

Игра класс. Если хотите поиграть в прятки с монстром, пошугать кракозябриков, побыть цундере для лепестков и поиграть в салочки с терминатором, то смело берите и играйте со своими друзьями, так же ещё веселее :)
TLDR: You can get the robot to suck you off Once you shoot his core enough times, he'll shut down temporarily, that is when you can assert your dominance and get him to suck you off while he is in the kneeling position, repeat a few more times till he explodes and falls flat on his face, this is when you can come from behind and finish. Prob the most fun I've had in a long time. 11 out of 10, would recommend.
We need more maps on different planets, more monsters, more weapon choices and upgrades. It would be nice if we could keep our maps on us and have another perk equipped. Also, having the ability to jump and also hide in lockers or in certain furnitures to escape monsters. If possible, to have the opportunity to have more players on certain maps. We have a big group of friends and only 4 players is capped :( So far, very fun and recommend !
