“I held off from buying Abiotic Factor because I felt like 30 dollars was a bit steep. After playing I would say the game is well worth the price and will more than make up for it in gameplay. Overall, I really enjoyed…”
“This game is simply excellent. This is also the second time I've spent over 100 hours, I played through on the Gamepass version but wanted to play again so wanted to support the devs. Imagine the feel of half-life, but…”
“Probably one of the best games I have ever played. As stated before, it is a hybrid of Half life and the SCP universe, done so well its genuinely shocking. The level design, progression, enemies, characters, locations…”

“Didn't know anything about this game, but I saw an online review mention it has the satisfying level design of Dark Souls and the exploration of Subnautica. So I took a chance. Not only is that true, but Abiotic Factor…”

“A survival craft game if it took place in the Half Life universe. With a steady support stream of updates from the devs and plenty to explore, kill, and create. Even more fun with friends.”
“If you don't have people to play with then don't buy it. It is an interesting world but it also doesn't feel engaging. Honestly some voice chat chatter especially in character would make it a great experience but i just…”
“Having so far played like maybe two thirds through the game I can't recommend Abiotic Factor enough. It's a game in a very populated genre and still manages to shine so brightly despite countless other games sharing the…”

“Hidden gem, incredible level design for survival game, interesting and spooky setting also. Exlporation is so good, it hurts (to hoard all the stuff).”

“best co op game ive played with friends performance needs fixing especially for players hosting though”
“bit laggy for a lowpoly game but 30$ and only 6 gigs for something so expanse. it's worth it.”
“Half Life 1 was one of the first games I have ever played and that was clearly inspiration for this one. I just love the eerie, underground facility atmosphere that only these 2 games have. The plot is very interesting…”

“This is one of my all time GOATS, it just has everything that I love and I've soaked up this world like a sponge. This game feels almost perfect, but it does lack in some areas. Combat can be a bit hit or miss, hitscan…”
“If you get in for the exploration and slow paced play, the leyak may ruin that fun for you, it did for me. I used console commands to spawn the holding chamber for it after a day of play in which I had not had as much…”

“TL;DR - It's fantastic. A wholly unique and shining star in the indie space. That is, if you can navigate its labyrinthian map and keep up with its occasionally punishing combat. I think this game is best summed up by…”
“I've been playing since almost the first phase of early access. It's definitely worth playing especially if you are playing with friends. They are continuing to update this game and add additional content and content is…”
“This is honestly the best survival game I've played. The only complaints that I have are that enemies are really tanky in the later sections of the game.”

“good game, a little grindy, but still good”
“Been through Portal Worlds back and forth, fought unknown specimens and all in confines of Australia, instead of New Mexico. Abiotic Factor basically turned Half-Life into a survival/story game that genuinely was fun to…”
“As a Survival Craft fan this is an incredibly fun and easy starter for those wanting to get into the genre. The game has a decent pace and plenty of fun crafting ideas to try. The main downside is how late in the game…”

— a player, Steam review · 58 hrs played“By far one of, if not the greatest, survival crafting games on the market. 282hrs, multiple playthroughs, and 100% of achievements, and I would do it all again. The world building is top notch, the art style is just right, the progression is smooth and meaningful. All and all…”
