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

Definitely worth the $10. I have 36.4 hours in Species: Unknown, and I’ve completed everything, maxed out all the upgrades, and unlocked everything there currently is to unlock. At this point, there really isn’t much left for me to do but I had a great time getting there. I played solo for the majority of the game, and it was still extremely fun and completely manageable. The different specimens kept the game interesting, and learning how to deal with and capture each one was probably my favorite part. I can’t wait for the developers to add new bosses, maps, equipment, upgrades, and more things to unlock. The game already has a really solid foundation and a ton of potential. For only $10, I absolutely recommend it.
Whats really unknown is where the rest of the game is. but its solid.

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 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.

The little time i have played this has been a blast. the monsters and your interaction with them is interesting and unique. cant wait to get deeper into it and run every mission
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.

It's so good, I love this game
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.
good
Event Horizon meets Alien isolation. great fun. a bargain at twice the price!
мультиплеер не работает. Да, я знаю то что есть соло режим, НО! я человек который любит играть с другими людьми, и как я понял эта игра подразумевается под нескольких игроков, мультиплеер не работает из-за EOS, я что только не делал, смотрел гайды, и т.п. (советы в стиме тоже смотрел, не помогло, тупо папки с EOS нету), так что играть больше не собираюсь, если ВДРУГ у меня всё заработает (не знаю как и когда это произойдёт), то тогда и поменяю отзыв (у кого есть идеи и советы, говорите)
