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!

runs well for an unreal engine game, you do have to tweak some settings and run the version "for lower end PCs" even on pretty modern hardware or else you'll get frequent crashes (this isnt just a me-thing, it happens with my friend, too) tons of content without being overwhelming, and solid character customisation. it's very satisfying to get yourself established, and the game is full of little Tricks and Tidbits you can learn if you're attentive (though you'll get the occasional thing that you gotta look in the wiki for). and theres room for every play style in a team (though some folks may want the heads up that for single-player you cant really avoid having some way of doing combat, especially late-game) the story-progression side of things is Alright. the ending was kinda ♥♥♥♥♥ tbh, the boss was a slog that did no damage but drained the hell out of your ammo and durability, so theres a lot of leaving mid-fight to replenish ammo and durability. i think ammo quanitity and durability should be generally more abundant all around, even just by a little bit. pretty much all the important plot threads were left unanswered and unresolved, which isn't always a bad thing, but felt pretty ass here. i get the feeling they did this on purpose for future dlcs, which like, idk. day-to-day, the writing is funny, and interesting. it's not a particularly life changing narrative, but you can't expect every game to be disco elysium, y'know? i'd advise against the game if you're Only In It for the story, but its a fun bonus if you're moreso in it for the gameplay, i mentioned the character customisation before, but when combined with the base building, multiplayer, and equipment variety, there's a ton of replayability here, and i'm fully intending on doing more playthroughs with friends. overall, highly recommend for survival sandbox fans. it has phenomenal multiplayer and is definitely best with a group, but i had plenty of fun playing solo, too. the story side of things might leave you a little underwhelmed, but it ain't terrible by any means. ps theres also a fantastic furry mod (cackle factor) if youre a freak like me
good👍
super lux
I would highly recommend this game , specially with friends , You get a wide range of areas to explore and build bases in and you get to choice how you want to fight things, the game as so many different elements that each person you play with can have there own speciallties things to do.. cooking, gardening, hunting. so many more...
My new obsession
Построил турбо туалет для телепортации фекалий пришельцев в другой мир. Игра понравилась!
SUPER FUN SO FAR runs flawlessly on arch linux just unlocked the hacking machine and its been a blast
Was amazing for 2/3 of the game and in the last third the difficulty made things really unfun as everything begin to hits too hard while weapon's damage doesn't increase by much if at all (fr I've unlocked laser guns, plasma flails, railgun crossbow but my best weapon was a pickaxe I unlocked 40 hours prior to that) weapons that do make the difference generally have sparse ammo while you need stacks of it just to explore a little... I still recommend it but I really wish the last part of the game was a bit more balanced and felt a little more complete.
It's good especially with friends
