Downloads
Elden Ring for Archipelago — the apworld, the runtime client, and the docs. Published on GitHub Releases, with stable and development builds kept visibly separate.
Take both halves from the same release
The apworld and the client .dll are a hash-matched pair. A
mismatched pair does not fail at the door — it connects, and then behaves subtly wrong. The
bundle below contains both halves from one tag, which is why it is the download for players.
If your client log says VERSION MISMATCH, that is this: redownload both from the
same release, and don't file a bug from a mismatched pair.
Latest release
v0.5.2 published 2026-08-29For players — the full bundle
apworld + client DLL + docs, one matched download
Everything you need to play. Unzip it and follow SETUP.md inside — roughly fifteen
minutes from here to a running seed. You also need Elden Ring on PC (Steam),
Archipelago, and the
ModEngine3 (me3) mod loader; the setup guide walks both.
For hosts — the bare apworld
generating a multiworld, not playing it
Just the world definition. If you are rolling a seed for someone else you need this and nothing
else — no game, no client DLL. Drop it in your Archipelago custom_worlds/ folder.
Or skip the install entirely and
build a seed in the options wizard, which generates and hosts it here.

Development build
devFor playtesting current work
Rebuilt automatically from the current world and client main branches. It can
change after every merge, is not a stable release, and records both exact commit SHAs inside
the bundle so a report can always be tied back to its source.
Known development-build difference: the private AP flower texture is omitted for now, so checks and AP shop slots use Elden Ring's Telescope icon. This is cosmetic; stable bundles still refuse to package without the flower override.

Where the project lives
GitHub — 4laric/er-archipelago
Source, releases, the player guide, known issues, and where to file a bug. This is the single source of truth for downloads: every other page linking this project, including this one, points back here.
Nexus Mods — Archipelago in Elden Ring
The mod page, screenshots, and the comment thread where most player feedback arrives. It links to the same GitHub release rather than hosting its own copy — a mirror goes stale, and a stale copy of this particular artifact produces exactly the mismatched pair described at the top.
