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

Great Game, so much fun, great mechanic.
Very VERY fun for the price, I would gladly pay more than I did for this game, I bought the supporter pack just because I think these devs deserve it and I really want to see what they can do. Graphics are decent, movement is decent, gameplay all works smoothly and I haven't run into any bugs or issues of any kind. It kind of reminds me of a mix of demonologist/phasmophobia and lethal company. Scary as hell atmosphere, cool contracts and difficulty modifiers, and fun as hell with friends! Early access so content is limited for now, but they really have something here and I absolutely cannot wait for them to get some more monsters to face and new maps to play on. The optimization for smoothness is a little lacking, I get 120+ fps minimum (capped it at 120 in-game) with gsync + vsync enabled in NVIDIA app in 4K resolution and maxed out graphics. It runs smooth enough with this configuration but can be a bit choppy and stuttery with no frame cap.

Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
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.

Fun Game
I am looking forward to future updates to this game. For an early access the atmosphere and different challenges are immense. I am hoping for way more maps, more monsters, more bounty contracts (mainly expanding on the different types of missions that are already currently in the game). It's terrifying, it's fun, it's challenging, and this game i can see potential in being great! I think it would also be cool to see more weapon types, tools and equipment. Mayyyyyyybe it would be cool too if there was some sort of upgrade that allowed you to select one more tool to take with you on the missions. maybe balance it out some how to make it not so over powered to do so.
The first time I personally bought a game early access on steam. It is such a fun and spooky experience im excited for more
Pretty good, only thing it really needs is more content but if thats the only complaint for an early game thats very promising.
