Yet Another Zombie Survivors Dead Terminal Map Guide

Confirmed role in the Bio Lab route

The official Version 1.0 release states that Bio Lab unlocks after completing Dead Terminal on Default mode. This is the source-backed progression fact for Dead Terminal. It is specific: completion on Default mode is the stated prerequisite for Bio Lab. It does not say that Dead Terminal itself unlocks Boss Rush, Infinite mode, or every later map.

Use the current map screen to confirm that your completion registered before troubleshooting Bio Lab access. If Bio Lab is still absent, check the exact completion mode and the installed version. The release note supports the prerequisite, not an alternate route. Keeping the fact narrow makes it useful.

What this source does not establish

The supplied official release does not provide Dead Terminal’s current hazards, enemy roster, boss attacks, spawn values, exact route, or item recommendation. This page therefore does not invent them. A map detail page should not fill a lack of evidence with generic survival advice. The current arena and tooltip remain the source for those mechanics.

Boss Rush is a separate system. The same 1.0 changelog says Boss Rush unlocks after Hardcore mode for each map, while an Infinite-mode correction refers to reaching 30 minutes in Endurance for each arena. Those facts should not be collapsed into Dead Terminal’s Bio Lab prerequisite. Separate rules make progress issues easier to diagnose.

A safe verification routine

First, complete Dead Terminal on Default mode as the official note states. Then check whether Bio Lab appears in the map selection. If you are documenting Dead Terminal itself, retain the current mode list, hazard descriptions, mission prompts, and version before publishing more detail. Do not state a boss name, timing, or numerical threat without a source.

The Bio Lab prerequisite comes directly from the full-release announcement. More detailed Dead Terminal advice will be added when it can be checked in the current game. For now, one accurate action is better than an unsupported walkthrough.
