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

incredible game 11/10 can't wait for more content
Presentation and gameplay are both perfect! the creatures you face range from little aliens to massive robots, its so diverse and cool to see a game not shy away from unconventional monsters and have them have their weaknesses too such as giving up on chases easily but are very aggressive, or having something that doesn't use the vents but uses drones to flush you out instead. Playing against these monsters is always so fun with the atmosphere being so crushing and disgustingly good. Now seeing as of right now there is only one map due to it being early access, I don't mind it, you get to familiarize yourself with the map and not worry about taking the pocket map (still a very useful tool) over something like the threat detector which has been my favourite tool. you also don't even need that tool as monsters make sounds depending where they are in the vent so you don't need to even worry about it. I really like how the corpses give you an early warning sign to what creature it is and that's so unique and a nice gameplay feature. My favourite creature to go against would have to be the Terminator, the crushing sounds of his feet, the sounds of the drones flying by, knowing if you get caught he's making a B-line direct to that/your position. he having an insta-kill for finding you crouched is fair as you shouldn't really be getting caught by him alone, his drones should do all the work finding you. The only reason he would find you alone is if you turn a corner to a long hallway and he just happens to spot you. his footsteps getting faster and more weight being put in them when you get spotted by a drone makes my damn heart sink although as he doesn't exactly run but being the size he is, him covering long distances isn't an issue.

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 2,402 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.

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)
underrated game
Looks good, plays good, feels good, scares good. 10/10 in my book.
Species Unknown is an Alien Isolation 2 in the making, before Alien Isolation 2 itself even debuts. This game deserves to be rated Overwhelmingly Positive, as it meets every expectation and more. Firstly, how to actually play. The game has helpful information desks scattered everywhere and the mission objectives are extremely clear. The environmental storytelling is phenomenal, being able to decipher which 'alien' will be your foe through the bodies in the environment. Is someone's forehead drilled in? Then it's who we like to call 'Wheatly'. Whilst on this topic, I do also find it nice that each creature's name is just a measly 'ID_00(x)', allowing the players to make their own fun names for them. The survival, it really does feel like a survival game, and the modifiers of later difficulties really amplify that, such as the power instability making you rethink your plan, fearing one slip up that wipes out half of your squad. No matter the player count, it still retains both the horror and fun aspects you'd expect to see from a co-op survival experience. Each alien has a diverse method of avoidance, killing, destruction and containment, leading to an extremely enjoyable gameplay loop that struggles to become stale. As the game is expanded upon, I can only see it getting better and better. The one map we have is beautifully made, each 'region' feeling distinct. It's not like other games where you'd require a map, because the environment changes plentifully the deeper you go, for you to learn each area's twists and turns. It also makes missions less tedious to have this preset map you can learn through experience. I can't compliment this game anymore than I already have, it's simply amazing, though there's a couple features I'd love to see: - More upgrades, whether that be to tier 2 weapons or other matters. Linking into this idea, I also think a ship upgrade that lets you take tier 2 weapons to the missions with you would be pretty neat, even though I love the pistol weapons so much. This would be nice for huge threats. - More tools to utilise! I'd love to see limited-use ammo crates that you can pull the lovely little ammo 'packs' out of just like the ammo box. Honestly, that animation is so nice I'd love to see those little packs with the handles be incorporated into it to be pulled from the crate. Another I can think of at the time of writing is a noisemaker device that can help with evasion; say you're being chased or searched for just after, but you smartly through this device into an opposing hallway to sneak away when it passes. All four of the current tools are extremely helpful both by themselves and as a team, and it should stay that way, each tool having great team synergy. - Laying on the ship beds, hiding in lockers in the on-map dorms (in the ones that have them) or some remotely similar mechanic for one-way areas, mostly the dorms in particular since it's just a rows of dorms down two one-way stalks full of vents. I'm not particularly fussed with this one though, just a niche yet neat idea. - We (friend group) thought up a new mission type that'd be pretty cool. Most of the following though is just waffle from me, the general premise though of 'what if we could board an enemy ship?' came from them: Sabotage The Illicit. In this scenario, a ship is transporting alien cargo for some sort of monetary profit or to use as some sort of bioweapon (and illegally, as per the name). There's many routes you could go with designing it, here's one just for the sake of developing the idea, but obviously this could be designed any way. To play this mission type, like the capture missions, you have to own a jamming module that prevents the ship from sending a distress call...either that or they can't because they know what they're doing is illegal. You go onto the ship and either intentionally release the specimen to kill off the crew for you, kill it in some fashion e.g using an emergency decontamination of its cell, or just kill and blow them up yourself with the engines overloading the core. Idk, feel free to expand upon that! 11/10
surprisingly good game. runs super well on old hardware. highly recommend!
Очень приятная визуальная составляющая, неплохо проработан интеллект у NPC, и сами монстры выглядят очень достойно. Игра не страшная, но пытается ею быть. Единственный по сути её недостаток - это малое количество контента. На данный момент одна карта и несколько довольно примитивных режимов игры (но тем не менее довольно проработанных) затянет вас насладиться этим коопом на часов 20, но не больше. Так что по сути, игре просто надо дать время. Если её будут двигать в том направлении, в котором она движется сейчас, то она обречена на успех.
really fun to play
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.
