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.

Gros potentiel !
ホラー苦手だけど殴れるなら怖くない!って人におすすめ。(ちなみにホラー苦手です) 基本的に、エイリアンに侵略された船を調査するぞー!って視点のゲームです。 任務は、標本(地球外生命体とかターゲット)のデータを持って帰る/仕留める/捕獲/船ごと爆破するの4種類で、今のところマップは一つ。 超絶理不尽なエイリアンもいるけど、どういう動きをするのかってのが書いてあるので、船の中の残骸や死体の形状でそれを調査し、特定し危険な行動を取らないことで結構回避できる。 それと、探知機はソロではマップを把握してないと絶対持たないほうがいいです。ミニマップはもっといてください・・・。 (袋小路に追い詰められてしにます・・・。) 純粋におもろいゲームだなぁ。と久しぶりに思いましたw でも、怖いのでソロではやりませんw

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.

This game is really good especially with friends, exited for the new map
im so sorry
гра дуже цікава, хоч і на сьогодні є тільки одна мапа, але монстри не дають заскучати, грав до цього в lethal company і знаєте, я отриав емоцій більше, ніж від lethal, але кількість контенту поки дає про себе знати, гра на момент написання цього коментаря сказав б на годин 15-20, після чого вірогідно сценарії почнуть повторюватись, дякую що приділили увагу моєму коментарю ! Трохи правлю коментар, гра я б сказав розрахована хоча б на 2-х гравців, адже є місії, які хоч і можна почати в соло, але пройти їх в соло або неможливо, або буде дуже важко і ви вірогідно просто вигорите поки будете це все проходити. Ще раз дякую за увагу !
this game has so much promise but after about 10 hours the fact that it only has one map and 5 monsters really starts to wear thin. please, please more updates. PLEASE.
Good
10/10 its fun
Finally an EA game that plays well, and didn't have any noticeable bugs.
Crazy detailed environment. Creepy game, with a great simple gameplay. Really fun. Can't wait to co-op this. Runs exceptional great for a UE5 game. I have a fairly old setup; 10900K with a RTX 3090 and I run around 200fps.
