Abiotic Factor Portal Worlds Guide: All 23 Explained

This Abiotic Factor Portal Worlds guide exists because the game never sits you down and explains the system in one place. You stumble onto a portal, walk through, and suddenly you're somewhere that looks nothing like the GATE facility, with no idea if the resources there work the same way. They mostly don't.

TL;DR: Portal Worlds, also called Anteverses, are self-contained dimensions outside the main Cascade Facility, reached through portals found while exploring. There are 23 named ones, each with unique enemies and materials. Resources on a timer reset weekly (currently midnight between Tue/Wed and Sat/Sun), but player-placed structures don't, and the main Facility itself never resets. The newest addition, Dunkeltaler Forest, arrived with the May 2026 Cosmic Companions update.

Abiotic Factor Portal Worlds guide: what they actually are (quick answer)

Portal Worlds are self-contained alternate dimensions accessed through portals scattered around the GATE facility, officially called Anteverses. Each one has its own enemies, materials, and sometimes its own boss fight, and most reset their natural resources on a weekly timer while leaving anything you've built untouched.

Key takeaways

• Portal Worlds are also called Anteverses. Both terms refer to the same system.
• There are 23 named Portal Worlds as of the current build.
• Resources reset on a timer, currently midnight between Tuesday/Wednesday and Saturday/Sunday. Structures and placed items don't reset.
• The main Cascade Facility itself never resets, unlike the Portal Worlds branching off it.
• Albatross hosts a major boss fight, IS-0117 (the Wayseeker).
• The newest world, Dunkeltaler Forest, arrived with the May 2026 Cosmic Companions update and ties into a crossover with the indie horror game Voices of the Void.

Overview

This guide covers Abiotic Factor (Steam appid 427410, Deep Field Games, Playstack) as it stands after the Cosmic Companions update. Reviews sit at Overwhelmingly Positive across more than 56,000 total. What follows covers what Portal Worlds actually are, how the resource-reset mechanic works, the full named list, and what's genuinely different about the newest addition. It doesn't cover a room-by-room walkthrough of each world, since 23 separate deep-dives would bury the actually useful information under repetition.

What Portal Worlds are and how you reach them

Portal Worlds are separate, self-contained dimensions that exist outside the main GATE Facility. The game's own internal terminology calls them Anteverses, and you'll see both names used interchangeably in-game and across community guides.

Access comes through portals you find while exploring the facility. Exactly how each one unlocks varies. Some just require finding the physical portal during normal exploration. Others are gated behind specific story progress, a particular item, or higher-tier equipment like an upgraded Keypad Hacker. There isn't one universal unlock condition, which is part of why the system feels underexplained the first time you encounter it.

How the resource reset works

The single most important mechanical detail: natural resources inside Portal Worlds reset on a timer, currently set to midnight between Tuesday and Wednesday, and again between Saturday and Sunday. That covers things like ore deposits, plants, and other harvestable nodes.

What doesn't reset: anything you've placed yourself, whether that's a structure, a stored item, or a base component. The main Cascade Facility is a separate case entirely, it doesn't reset at all, ever, which is exactly why Portal Worlds function as the game's renewable-resource layer instead of the facility itself.

Practically, this means treating Portal Worlds as a farming rotation makes more sense than treating them as a one-time loot run. If you clear a world's resources right before a reset window, you're leaving value on the table.

All 23 named Portal Worlds

Albatross, Canaan, Dunkeltaler Forest, Far Garden, Flathill, Furniture Store, GATE Arch Defense Facility, North Pole, Praetorium, Rise, Royal Range, Shadowgate, Some Distant Shore, Temple of Stone, The Mycofields, The Night Realm, The Pool Room, The Train, The World in the Mirror, Torii, Village Den da'ko Yeer, Voussoir, and Winter Cabin.

Two are worth calling out specifically. Albatross is the site of a major boss encounter, IS-0117, nicknamed the Wayseeker, a large eldritch entity fought across three phases (tracked by how many floating hands are visible). It's a separate fight entirely from the Tarasque, which stays inside the main facility's Containment area.

Portal World biomes range from recognizable, if hostile, Earth-like settings to fully alien environments like this one. The variety is the point, each world is meant to feel distinct.

North Pole is a snowbound Portal World, distinct in tone from the alien or ruined settings some of the others lean into. It's a useful example of how varied the roster actually is, not every world reads as a horror-tinged dimension.

North Pole leans into environmental survival mechanics, cold resistance and shelter, rather than the combat-first threats some other Portal Worlds emphasize.

Dunkeltaler Forest: the newest addition

Dunkeltaler Forest arrived with the May 2026 Cosmic Companions update, accessed via a portal inside the Hydroplant, near the path to Robotics. It ties thematically into the "Alpen Signal Observatorium," which is a direct crossover reference to Voices of the Void, an indie horror game about monitoring signals from an isolated research station. It's also the one Portal World on this list with a hard item gate: you need a Neutrino Mapper, crafted using materials from Voussoir, before the portal activates.

The same update brought a broader set of changes alongside the new world: a chemistry system built around Distillation and Chemistry Benches, a Pets 2.0 overhaul supporting multi-pet carrying and tameable Peccaries, more than 100 new items, new Blunt-category weapons, and new mobility tools. Dunkeltaler Forest itself is the piece most relevant to this guide, but it didn't ship in isolation.

Tips

Time your resource runs around the reset window

Since the Tuesday/Wednesday and Saturday/Sunday midnight resets only refresh natural resources, plan farming trips for right after a reset rather than right before one.

Don't assume a Portal World's difficulty from its aesthetic

A cozier-looking world like North Pole can still have real survival pressure from cold and terrain, while a more alien-looking one might be more combat-focused than environmental. Judge each world on its own mechanics, not its color palette.

Bring gear appropriate to Albatross before attempting the Wayseeker

IS-0117's multi-phase fight is a different kind of challenge than most Portal World exploration. Treat it as a dedicated boss encounter, not something to stumble into mid-resource-run.

Keep an eye on new-world announcements

Since Dunkeltaler Forest shows the developer is still actively adding new Portal Worlds, checking patch notes periodically is worth it if you've already cleared the existing 23.

Common mistakes

• Treating the facility and Portal Worlds as equivalent renewable sources. Only Portal Worlds reset naturally; the main facility does not.
• Clearing a Portal World's resources right before a reset. You're leaving value that would've refreshed anyway.
• Confusing IS-0117 with the Tarasque. They're separate encounters in separate locations with separate mechanics.
• Ignoring per-world access requirements. Assuming every Portal World unlocks the same way leads to wasted time hunting for a portal that's actually gated behind a story step or item you haven't found yet.
