Modeled estimate, not a reported figure. How we estimate →
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
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.
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.
Reviews, worldwide (the counter carries no country): 30/day in the week to Sep 1 → 34.43/day in the week after.
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.
About

Home to the world's greatest minds, GATE operates a global network of secretive research laboratories, spanning every field of scientific study - and the realms beyond.
As a GATE employee you extend the bounds of human knowledge, and seek to explain the unexplainable - including anomalies and paranormal entities: from gravity-distorting artifacts to supernatural creatures with an unbridled instinct for violence. Safety, security, and secrecy are of the utmost importance… usually.
After a catastrophic containment breach, your workplace has become a cosmic battle zone: anomalous entities are on the loose, enemies from other dimensions are invading via portals, and an arcane military sect - known as The Order - is targeting personnel and entities indiscriminately, aiming to seize artifacts and put an end to the chaos.
Containment procedures have failed and help isn’t on the way. Stranded miles beneath the surface, it’s up to you and your fellow scientists to band together, plan your escape, and make this underground complex your new home - for now.

Abiotic Factor brings a 90’s sci-fi twist and rich character progression to the multiplayer open world survival crafting genre. Up to 6 players can choose their PhDs, build their scientist, gear up, and explore a massive subterranean complex, filled with supernatural artifacts, transdimensional foes, and science experiments gone awry.

Between alien threats hunting their next meal, trigger happy soldiers, and the world’s most advanced robotic security forces attacking personnel working overtime, there’s no shortage of danger. As a scientist, fighting isn’t your forte, so you’ll need to put your PhD to work to outwit your opponents: craft ingenious and outlandish tools, weapons and gear, from simple nets and wooden bats to laser-cannons and elaborate traps - everything your big science brain can muster!

Make yourself at home - you’re here for the long haul. Scavenge resources from vacant offices and empty labs, raid vending machines, and steal company property to build a new base of operations as you explore the facility. When it’s time for a change of scenery, pack up your belongings and move them across the facility using handcarts, forklifts, SUVs, teleporters, and more.

Don your lab coat and earn your PhD: from Phytogenetic Botanist to Defense Analyst and Archotechnic Consultant (and many, many more), each with its own advantages essential to survival. Combine traits and skills, then level up to earn perks and abilities with your fellow scientists to forge a formidable scientific force.

Working at GATE may have been a dream job, but dying here wasn’t part of your five year plan. Explore this massive underground facility as well as many worlds beyond and take full advantage of the most advanced technology unknown to mankind in this interdimensional sci-fi adventure!

This is hands down one of the greatest games i have ever laid my eyes upon. i am blessed to be able to play such a masterpiece.
第一次遇见这么好玩的恐怖游戏,近年来难得一见的精品。 ——简练且富有黑色幽默的对白快速地塑造了多位戏份不多却出彩的角色。 ——极其优秀的小箱庭设计,简直媲美《黑暗之魂1》那般的峰回路转,且与之相比,小而精的设计再加上载具、传送要素,让跑图难度也降低了不少。 ——巨量游玩要素,包含:养成、合成制作、探索、建筑规划、战斗、塔防等等。流程极长,且各种要素都会随着探索进度渐进,体量完全对得起价格。 ——优秀的美术和氛围塑造。虽然是粗糙的像素画风,却还是以扎实的美术功底塑造了相当多令人身临其境的经典场景:冰冷的实验室、肃穆的办公楼、繁杂的工厂、停电的诡异安防区、离奇的外星世界等,甚至得益于”异宇宙“设定,还有像是”被丧尸包围的家具城“、”遍布邪教徒的中世纪黑暗村庄“之类的怪奇场所存在。风格涉及了SCP、后室、半条命以及大量恐怖游戏IP,却又能够自洽融合。 ——害虫很可爱,西猯很帅。有几十种宠物可以养在家里,也可以领出去帮助战斗探索,宠物系统超赞! 以上,喜爱之情溢于言表了。

absolutely love this game started playing it solo and didnt really know what i was doing, played for about 20 hours before taking a break, then when i came back to it some friends wanted to play too, so we started a new world together and played regularly with one another and enjoyed exploring and learning everything together. then after over 100 hours together, exploring, fighting, building, we beat the game together, and for me, its a first time ever finishing a game with friends like this, and it was AMAZING, so much fun, everything in this game is so cool to look at and explore, everything you find feels so lively and unique but still connected together
I'm not a survival game player, or enjoyer for that matter. I often find the grind to stay alive coupled together with obscure progression is simply not enjoyable. Abiotic Factor is the exception. Rarely throughout my session did I feel like I was "surviving". I was progressing in a semi-linear way. I won't go into depth regarding its context, but aside from me feeling lost in the maze-like facility I've rarely experienced anything negative. It is truly and honestly a fantastic game. Play it if you like survival games with proper progression. Or if you like half life I guess.
Было довольно интересно прям до самого финала. А сколько отсылок на другие произведения!

Обожаю вещи, внимательные к мелочам. А здесь даже звук у поврежденных ловушек другой.
ABSOLUTE AMAZING GAME 10/10
Highly captivating sci-fi story following an "SCP foundation-esque" organization with extremely detailed worldbuilding, graphically presented in a HL1 style. One of the most refined survival crafting games I've ever played. Hundreds of hours of content in the main game. Easily in my top 10 games of all time, probably top 5. Make no mistake, it's worth your time and $35 is a bargain.
