Abiotic Factor

Abiotic Factor drops you in a research facility after an experiment goes wrong, and somehow makes scavenging office supplies feel as tense as anything else on this list. My Helldivers 2 crew tried it expecting a quick laugh at the science-lab setting, and stayed three hours barricading a supply closet against test subjects, which tells you everything about how the loop actually plays. Crafting, base defense, and constant needs management sit at the center, and it holds up fine solo if your group can't make it that night. It hit PS5 in 2025 and runs smoothly, no rough console port issues to flag. The humor helps. If you want a survival game with actual jokes in it, this is the one.

Set in a collapsing research facility overrun by dimensional anomalies, Abiotic Factor has one of the more original survival premises on Steam. The crafting and resource scavenging feel purposeful rather than routine, and the sci-fi setting gives it personality that the genre's usual forests and post-apocalyptic wastelands lack. It missed the top ten because the Deck experience, while functional, is not quite as polished as the best entries here. Worth watching if you are looking beyond the classics.

The setting alone makes this worth mentioning. A science facility disaster that plays less like a zombie game and more like a Half-Life episode where you also have to find food and build a defensible base. I had not heard of it until a friend recommended it and we ran a session on a Friday night that went significantly later than planned. Six players maximum in a private setup, roles emerge naturally from what each person gravitates toward, and the scavenging loop has that one-more-room quality that survival games need to sustain long sessions. Still in active development, which means some rough patches, but the co-op foundation is solid enough to recommend confidently.

My co-op group spent most of last year playing Helldivers 2, and when we started looking for something with more of a systems backbone between sessions, Abiotic Factor came up. The premise sounds absurd: survive inside a research facility that has gone catastrophically wrong, scavenging office furniture for materials and fortifying rooms against whatever used to work in the labs. In practice it clicks fast. The survival loop is real, the crafting has logic to it, and the setting means every room you push into is genuinely unknown. It works solo too, but this is one where having a friend coordinating on a headset changes the experience substantially. Fresh, strange, and one of the better recent PS Plus additions in the genre.

This one caught me by surprise. A co-op survival game set inside a science research facility, scavenging labs and cafeterias for materials while something has clearly gone very wrong with the experiments. The setting does something the genre usually doesn't: it makes resource scarcity feel plausible. You are not punching trees in a forest, you are raiding supply closets in a collapsing government installation. The shared progression is tight and the co-op structure feels built for groups of three or four who actually talk to each other. It is fresher than most things on this list, which is why it ranks above games with bigger franchises and longer track records.

Abiotic Factor is the newest game on this list and the one most likely to surprise people who have not heard of it. You are CERN scientists trapped in a facility overrun by anomalies, building a base from office furniture and cafeteria equipment while trying to progress through increasingly dangerous sections of the complex. The objectives are clearer than most survival games, which helps a group maintain momentum across a session rather than drifting into aimless exploration. Private server setup is practical, the tone is refreshingly strange, and it supports up to six players. It narrowly missed the main list because it is newer and less proven across repeated LAN sessions, but it is worth watching.
