Plans can change before release
Official NPC posts frame first-stage NPC work as planned and subject to practical delivery decisions.
Expected / Planned
Build 43 features discussed by official posts
Planned
NPC systems and survivor behavior
Older official planning posts discuss survivor AI, group behavior, jobs, combat support and off-screen narrative systems as NPC goals.
Planned
Narrative and meta-world systems
The Indie Stone has discussed storylets, NPC movement through known buildings and roads, and generated survivor backstories.
Planned
Stage-one scope still needs caution
The first NPC build may not contain every long-term NPC idea. Treat individual features as planned until shown in current official release notes.
These are planning directions from official posts, not a locked patch-note list. The first Build 43 release could narrow or stage the scope.

Build 42 is the current content and support context for live survival planning. Build 43 is the future NPC-focused milestone. For current map, trait and base decisions, use Build 42 pages; for future NPC release status, keep checking official Build 43 updates.

Speculation Boundaries
What is still not confirmed
Unconfirmed
Exact release month
No official Build 43 release date has been announced, so any exact month or countdown should be treated as community speculation.
Unconfirmed
Final feature list
Community lists can mix old plans, developer experiments and guesses. This page only treats official posts as source material.
Unconfirmed
Full NPC simulation at launch
Official writing has described staged delivery, so assuming the complete NPC vision arrives in one update would be unsafe.
