With 600+ custom zombies, horror movie icons, and pitch-black nights, this mod delivers terror that vanilla 7D2D only hints at. The build below tracks the V3.3 release line.

The Asylum features over 600 brand-new zombie variants, ranging from shambling horrors to terrifying boss creatures. Each zombie type has unique behaviors, attacks, and spawn conditions.
Face off against cinema's most terrifying villains:
These Horror Icons should be avoided at all costs unless you're extremely well-equipped and confident.
Beyond the horror icons, Asylum introduces demonic entities:
Choose your survivor archetype at game start, each with unique bonuses and playstyles tailored to the horror survival experience.
From 21:00 to 05:00, visibility collapses into near-total blackness. You'll need to:
Thick fog rolls across the ground, limiting visibility even during daylight. If the atmosphere becomes too intense, there's an optional no-fog patch available.
A sprawling quest tree that guides you through the horror experience, revealing lore and unlocking new content as you progress.
After reaching level 10 in base attributes, unlock five new Infernal Attributes that extend your character's power beyond vanilla limits:
Hunt for legendary equipment that can give you an edge against the most terrifying foes.
An arsenal designed for horror survival, from improvised weapons to powerful demon-slaying tools.
New vehicles including a UFO for those who discover it.
Advanced storage systems to manage your survival supplies.
If the dense fog is too much, download and install the no-fog patch from the same source.
Yes. The Asylum team updated its 3.2.2f build for V3.3 on 10 October 2026. Use the 7D2D Mod Launcher, which version-checks before installing so you don't end up on an incompatible client, and leave Steam's beta branch on None: since 5 October 2026 Steam's default is V3.3. The one-click Asylum on 7d2d.net servers is Asylum 3.3 on game V3.3 since 10 October 2026; a server still on the older Asylum 3.2.2 needs players on the v3.2.0 branch.
Plan for 12 GB minimum on a 4-player server, 16 GB for 8 players, and 20 GB for the full 16-player setup. The Asylum is heavier than vanilla because of the 600+ custom zombie entries, the 750+ POI pieces, and the fog and lighting systems. The OS adds another 1-2 GB on top, so a 12 GB rented VM running Linux is usually a tight fit; 16 GB is comfortable. See performance tuning for tradeoffs.
No. The Asylum changes biome generation, POI placement, zombie spawn tables, and the progression tree. An existing world generated under vanilla or another modpack will not migrate. Generate a new world after installing the mod. The Mod Launcher will warn you if you try to load a non-Asylum save. The save migration notes cover the failure modes if you try anyway.
Yes. The Asylum is a client-side overhaul: every connecting player needs the mod installed at the same version as the server. Mismatches trigger asset-bundle-failed-to-load crashes during world transfer. The Mod Launcher version-pins the build, so distributing a launcher modpack link is the cleanest way to keep a group in sync.
Yes. Easy Anti-Cheat blocks the custom code-injection that Asylum uses for its boss-spawn logic and the true-darkness lighting layer. Disable EAC in your launcher options before joining. Dedicated server hosts typically disable EAC server-wide in serverconfig.xml; players still need to disable it client-side.

These numbers are counted from the configuration files of Asylum 3.0.1, the build we hosted before 3.2.2, not from its changelog. 7 Days to Die overhauls work by patching the base game with XPath operations, so the mod files are a literal list of every change it makes.
| What | Count |
|---|---|
| Ships as | 76 separate mods |
| Total changes to the base game | 6,971 |
| Of that, made by the Asylum Core mod itself | 556 (8% of the pack) |
| Values changed | 410 |
| New entries added | 5,817 |
| Entries removed | 491 |
That split is worth reading carefully. What you install as Asylum is a curated pack, and the figure above covers everything in it. The Asylum Core mod, the part the Asylum team writes and versions itself, accounts for 556 of those changes. The rest comes from the other mods bundled alongside it, which is normal for a pack of this kind and is exactly why the two numbers are shown separately here.
Where those changes land:
In short: Asylum adds far more than it edits (5,817 new entries against 410 values changed), and the bulk of that lands on spawn groups.
