Expedition Into Darkness Release Timeline
Public milestones from open alpha through playtest waves toward the planned Q4 2026 window.
Players keep asking the same calendar questions about Expedition Into Darkness: has the full game shipped, when is it planned, and what happened between trailers? This timeline answers at a high level using public Steam and studio messaging. It does not invent exact ship dates inside the quarter. The full release is planned for Q4 2026 on Steam PC (app 3126410). Until then the game remains upcoming, with periodic demos and public playtest windows—not a finished retail ship.

Timeline at a glance
| Phase | Window / status | What players should do |
|---|---|---|
| Open alpha | Roughly Mar–Apr 2025 | Early feedback; expect heavy iteration |
| Dec–Jan playtest | Dec 11 – Jan 5 (public playtest window) | Combat/crafting themes; see Patch History |
| Team expansion delay | Previously aimed near Sep 2025; postponed | Wait for studio hiring / capacity updates |
| June–July playtest | June 15 – July 7 2026 (public playtest window; closed after) | Moor-focused sessions; signup waves ended |
| Wishlist / Steam page | Live; Planned Release Date Q4 2026 | Wishlist, watch trailers, prep guides |
| Full release window | Planned Q4 2026 | Verify Steam when a day is announced |
| Post-launch patches | After the full release | Convert Patch History to numbered notes |
Nothing in that table claims the full game has shipped. Closed public playtest windows are temporary access, not retail.
Dated public milestones
Open alpha (Mar–Apr 2025)
An early open alpha window let a wider audience stress co-op extracts, camp crafting, and ruin navigation. Treat footage from this era as historical: combat timing, maps, and enemy mixes have continued to iterate in later public playtest windows.
December–January public playtest window (Dec 11 – Jan 5)
A later public playtest window ran from December 11 through January 5. Community notes from that era (often discussed around early 1.0.0–1.0.8-style builds) cover timed/block feel, crafting grip multipliers, exit bugs, animation jank, missing controller support in early builds, and performance—framed as themes on Patch History, not forged official changelogs.
Team expansion (postponed from Sep 2025)
Studio messaging previously pointed at team expansion timing near September 2025; that timeline was postponed. Capacity and hiring updates can shift playtest cadence—do not treat an old hiring date as a launch date.
June–July 2026 public playtest window (closed)
A public playtest window ran June 15 – July 7 2026, with strong Moor-focused coverage. That window is closed after the end date. Signup for that wave is over; watch Steam and Discord for the next signup waves rather than assuming permanent access. Prep habits still live on the Playtest Guide.
Steam planned release: Q4 2026
Steam currently lists a Q4 2026 planned release for app 3126410. That is a quarter window, not a promised Tuesday. Recheck the store page when the studio narrows the date.
Phase notes (ongoing habits)
1) Wishlist and orientation
- Read the Game Overview for pillars: co-op extract, permadeath, gear crafting, base upgrades.
- Confirm hardware on System Requirements.
- Skim Guides and Getting Started so vocabulary is ready.
2) Between public playtest windows
Windows open and close. After a window ends:
- Confirm access rules for the next wave (Steam signup, Discord pings).
- Run the Playtest Guide night-before sheet when a new signup appears.
- Seat the squad with Party Planner.
- Pack kits via Loadout Planner.
- Enforce Extraction Checklist.
- File feedback the same day while a window is open.
3) Demo availability (when Steam offers it)
Demos are marketing and onboarding tools, not proof of retail readiness. Treat progress as temporary. Teach extract habits early so launch-week friends do not donate characters to greed.
4) Approaching Q4 2026
As the planned window nears:
- Recheck Steam for a narrowed date if the studio provides one.
- Re-verify recommended 16 GB RAM comfort for co-op nights.
- Refresh Builds and Map pages as systems freeze closer to ship.
- Expect louder marketing; keep comparing claims to official channels.
5) Full release and after
When the full release eventually lands (still future-facing), this timeline should gain a concrete date entry. Post-launch, Patch History becomes the home for real numbered notes. Until then, anyone treating a closed public playtest window as the finished game is wrong.
Myth vs. fact
| Myth | Fact |
|---|---|
| ”It is out on Steam to buy as 1.0 now” | Planned Q4 2026; public playtest windows are not full launch |
| ”The June 2026 window means permanent access” | June 15 – July 7 2026 public playtest window; closed after |
| ”Q4 means a specific Tuesday” | Quarter window only until a day is announced |
| ”Alpha loot is forever” | Wipes and build resets can happen |
| ”Trailer equals current combat” | Playtests iterate defense timing and encounters |
| ”Five randoms need no roles” | Use Tools pages or expect chaos |
Year-shaped expectations (editorial)
Without inventing studio secrets, a healthy community cadence looks like:
- Between tests: study overview, tools, and requirements; recruit a stable squad; watch for next signup waves.
- During tests: short scout run, then disciplined extracts; notes over grind.
- After tests: update personal checklists; read Patch History themes.
- Entering Q4 2026: verify Steam daily the week a date drops; avoid fake key sites.

Keeping the timeline honest
We will edit this page when Steam’s “Planned Release Date” string changes, when a concrete day is announced, or when playtest cadence materially shifts. We will not pad the calendar with rumor weeks. If a content creator claims an earlier surprise full launch, wait for the store page to agree.
Bottom line
Expedition Into Darkness sits in a clear pre-release arc: open alpha and public playtest windows for iteration, a closed June 15 – July 7 2026 wave behind us, and a Q4 2026 full-release target still listed on Steam PC. Spend the waiting time building squad habits—roles, kits, extract calls—and watching for the next signup wave so the eventual launch week is about wonder in the ruins, not about learning that carried loot disappears the hard way.

Frequently Asked Questions
Quick answers to the most common questions.
When is Expedition Into Darkness releasing?
Steam currently plans a Q4 2026 window (app 3126410). No exact day is promised on this wiki until the store page lists one.
Is the full game available to buy as a finished release?
No. It is upcoming. Public playtest windows and demos are temporary access before the planned Q4 2026 launch—not a finished retail ship.
What was the June 2026 playtest?
A public playtest window ran June 15 – July 7 2026 (Moor-focused coverage). That window is closed after the end date; watch Steam and Discord for the next signup waves.
Were there earlier playtest windows?
Yes. An open alpha ran roughly March–April 2025, and a public playtest window ran December 11 – January 5. See Patch History for Dec–Jan theme notes.
What should I do while waiting?
Wishlist on Steam, verify system requirements, assemble a squad, practice planning with the Tools pages, and follow signup announcements for the next public playtest window.
Do playtests mean launch is imminent?
Not necessarily. Public playtest windows can happen well before a quarter-long release window. Treat them as feedback opportunities.
Where are recent gameplay changes tracked?
See Patch History for playtest themes such as combat timing, crafting grip feel, maps, and enemy types—without invented official patch IDs.
Will this timeline get an exact date later?
Yes—when Antediluvian Interactive publishes one on Steam or the official site, we will update this page.
