Gameplay
Actual gameplay: the desk at 11:42 PM — the sack with eleven letters, three stamps in the drawer, and the office log. Reading is free. Answering is not.
Gameplay
Actual gameplay: a letter from Callie Voss, and the Write Back panel — five tones (Plain, Warm, Formal, Wry, Honest) and a 60-ink budget.
Dead Letter Office is a playable night-shift narrative game generated in Neta Studio for Welcome to the Neighborhood — a tightly-drawn Ravenswood, Chicago world where four people in the same orbit of games, coffee, and late-night tacos work out whether proximity becomes something more. You sort the 11:42 PM sack under the Metra embankment, where undeliverable mail is meant to be destroyed. Some nights, something comes back.
Eleven letters, three stamps, one shift. Read a letter, choose a tone — Plain, Warm, Formal, Wry or Honest — and write back with the ink you have. Seal and dispatch, burn what you cannot answer, and clock out before the night swallows the office. Every letter, reply and return is written live by an LLM as you play — no two shifts play the same.

Game Features
- Live LLM Narrative — Every letter in the sack is written live: the correspondents, their histories, and the replies that come back are generated in real time by Neta Studio's AI pipeline (deepseek-v4-flash real-time narrative). No two shifts play the same.
- Night-Sort Letter Sack — Eleven undeliverable letters arrive at 11:42 PM. Reading them is free; answering costs ink. Choose which broken threads deserve your three precious stamps.
- Five Tones, One Inkwell — Reply Plain, Warm, Formal, Wry or Honest. Every tone steers the return letter — and the neighborhood — in a different direction, with a limited ink budget per shift.
- Threads That Write Back — Dispatched replies can return as new letters in later shifts. Some answers come back to sender. Some senders come back too.
- Burn Bin & Consequences — Letters you cannot answer can be burned. What you burn, what you answer, and what you leave unread all shape the campaign and the people on the other end of the mail.
- Twelve-Shift Campaign — One night at a time under the Metra embankment: save your shift, clock out, and keep the threads alive across twelve nights of Ravenswood's strangest mail.

Production Process Breakdown

Stage 2: Game Design & Artgpt-image-2claude-opus-5
AI designs the game from that world: the night-sort premise, the eleven-letter sack, the five-tone reply system with an ink economy, the burn bin, and the twelve-shift campaign with save and continue — plus the Dead Letter Office box art and a 16:9 cover key art generated in a single pass.
