Expedition Into Darkness System Requirements

Before you join a demo or alpha window for Expedition Into Darkness, confirm your PC can run the build. The numbers below come from the Steam page for app 3126410. The game is a planned Q4 2026 Steam PC release and is not fully launched yet—specs can still be revised, so recheck the store page when a new playtest drops. Pair this article with the Playtest Guide, the Game Overview, and practical run prep on the Tools Hub.

Official Steam specifications

Both tiers require a 64-bit processor and operating system.

Minimum

Component	Requirement
OS	Windows 10
Processor	AMD Ryzen 5 3600X 6-Core or similar
Memory	8 GB RAM
Graphics	Radeon RX 580 Series or similar
Network	Broadband Internet connection
Storage	8 GB available space

Recommended

Component	Requirement
OS	Windows 11
Processor	AMD Ryzen 5 3600X 6-Core or similar
Memory	16 GB RAM
Graphics	Radeon RX 580 Series or similar
Network	Broadband Internet connection
Storage	8 GB available space

Read carefully: CPU and GPU targets are the same class on min and rec in the current Steam listing; the big jump is OS (Win10 → Win11) and RAM (8 GB → 16 GB). If you are near the minimum RAM line, close browsers and overlays before co-op nights.

What “or similar” means in practice

Steam’s “similar” language covers Intel / NVIDIA equivalents in the same performance band as a Ryzen 5 3600X and an RX 580-class GPU. Exact frame rates will vary with resolution, party size, and how busy a ruin is with particles, fog, and creature packs. During playtests, prefer stability over max settings—feedback is useless if you are hitching through every fight.

Pre-playtest hardware checklist

Use this table the evening before a test window:

#	Check	Pass?
1	OS is 64-bit Windows 10 or 11	[ ]
2	CPU roughly matches Ryzen 5 3600X-class performance	[ ]
3	RAM meets 8 GB minimum; 16 GB preferred for comfy multitasking	[ ]
4	GPU roughly matches RX 580-class or better	[ ]
5	At least 8 GB free SSD/HDD space (more headroom is kinder for patches)	[ ]
6	Wired or stable Wi-Fi broadband ready for online sessions	[ ]
7	GPU drivers updated; Steam download cache healthy	[ ]
8	Headset / mic tested for co-op calls	[ ]
9	Friends verified on Party Planner seats	[ ]
10	Wishlist / playtest access confirmed per Playtest Guide	[ ]

Network and co-op notes

Broadband is listed for both tiers because expeditions are built around online interactivity. Expect voice coordination even if you also use Discord. Lag does not only hurt shooters—timed defensive windows and tight hallway fights feel worse with spikes. If your connection is unstable, host duties or deep push objectives are poor choices; run material-farm routes and leave early using the Extraction Checklist.

Storage planning

Eight gigabytes is the Steam storage line today. Leave extra free space for:

• Playtest patches that land mid-weekend
• Steam shader / depot overhead
• Recording software if you capture feedback clips

SSD installs usually make stutter less painful in asset-heavy ruins, even when not mandated.

Settings advice for first sessions

1. Start on a medium preset; raise visuals only after a stable extract.
2. Cap frame rate to reduce heat on older RX 580-class cards.
3. Disable heavy overlays if you notice hitching.
4. Keep a second monitor for Loadout Planner and checklist pages if performance allows.
5. After each session, note hitch locations for your own feedback—useful alongside themes tracked in Updates.

Laptop caveats

Many laptops advertise CPU names that look desktop-adjacent but run cooler, slower sustained clocks. Treat marketing names skeptically. Plug in power, set a performance profile, and test in a short scout run before a five-player deep push. If temperatures throttle, lower shadows and effects first.

Accessibility of information (not controls)

This page covers hardware only. For onboarding and systems, use Getting Started and the Guides hub. For spatial hazards that can tank performance (gas, particle-heavy rooms), keep Map notes. For release timing expectations, see Release Timeline.

When specs change

Developers sometimes raise requirements as fidelity climbs toward launch. If Steam edits the table:

1. Update your personal checklist.
2. Re-verify friends before the next playtest.
3. Skim Patch History for related performance themes.
4. Do not assume a year-old clip’s settings still apply.

Quick verdict

If you are on Windows 10/11, a 3600X-class CPU, 8–16 GB RAM, an RX 580-class GPU, 8 GB free, and broadband, you meet the published bar for trying playtest builds. Aim for the 16 GB comfort tier when you run Discord, browser wiki tabs, and a five-person call together. Then spend your mental energy on roles, kits, and extract discipline—not on fighting the hardware.
