Project Zomboid Build 42 — Feature Map for 42.19 (Current Unstable)
Build 42.19 · farming months, character voices, maps, Discord options, and official main-menu Multiplayer / Co-op
Current status vs early preview claims
Build 42 is a large systems update: multi-level world support, deeper crafting (including blacksmithing), living animals, seasonal farming, fluids, lighting work, and more. Early fan pages mixed roadmap language with unfinished tools. This table keeps only claims that still hold on 42.19 or that must be retired.
| Topic | Early page claim | Build 42.19 reality |
|---|---|---|
| Multiplayer | “Initially disabled”; wait for stable 2025 | Main menu exposes Multiplayer and Co-op. The client shows a Build 42 multiplayer test-build warning. Still Unstable—not a finished stable release date. |
| Character voices | Fake labels like “Deep / Raspy / Mature” | Eight named styles: Bob, Casey-Jo, Chris, Hank, James, Janine, Kate, Maryanne, plus a pitch slider (−100 to 100) and demo button. |
| Farm seasons | Hops = summer; Broccoli = fall | Hops: sow Aug–Oct, best Sep, bad Jun–Jul. Broccoli: sow Feb–Jul, best Mar/Jun, bad Sep–Jan. See Farming tab. |
| Fluid mixer toy | Hardcoded +10 happiness / −10 thirst / gasoline layers | No such calculator in this guide. Fluids are a real container system—use in-game transfer UI, not invented mix stats. |
| Base “calculator” | High floors always safe; warehouses always have basements | Security is lot-specific. Check stairs, exits, windows, and whether a basement is a random house roll or a fixed map lot. |
| Discord | Trigger in-game events / run radio-TV scripts | Server options cover global text chat integration, bot token, chat channel, log channel, command channel—not a freeform event/radio script host. |
| “32-floor skyscrapers / infinite wilderness” | Presented as fixed current specs | Vertical expansion and multi-level support are real themes. This page does not publish an unverified max floor count or “infinite” wilderness claim. |
How to open Build 42 Unstable
- In Steam: Project Zomboid → Properties → Betas → select the Unstable branch.
- Back up any Build 41 saves and configs you still need. B41 and B42 worlds are not interchangeable.
- Assume most B41 mods need an update. Prefer a clean mod list for first-time testing.
- For multiplayer, treat every Unstable patch as a possible wipe of ongoing sessions.
World: vertical space, maps, bases
Vertical expansion
Build 42 invests heavily in multi-level play: taller buildings, basements, and underground-adjacent spaces. That changes loot routes and base planning (long climbs, more stairs to defend, more fall risk). Treat any specific “N floors guaranteed” claim as marketing unless you verify the lot in your own save.
- Basements — Many homes can roll procedural basements; some POIs use fixed basement lots (not the random house pool). See the Muldraugh map notes for that distinction with concrete pins.
- Height ≠ free safety — Upper floors reduce some ground traffic but still need stairs control, noise discipline, and a second exit plan.
- Generators — Do not run generators indoors or in sealed garages. Toxic exhaust is a lethal systems rule, not a “close the door for noise” tip.
Map regions shipped in 42.19
Current main map areas in the client include:
Classic belt
Muldraugh, West Point, Riverside, Rosewood, March Ridge, Valley Station
Western expansion
Echo Creek, Ekron, Brandenburg, Fallas Lake, Irvington
Other
Challenge maps (separate from open-world KY towns)
Louisville remains part of the broader Knox Country experience for many players; treat spawn availability and exact lot data as client/spawn-file questions, not as a promise that every town is a default spawn button.
Base scouting checklist (no fake score)
Instead of a scored “best location” widget, walk the lot:
- Count and control stair cores / fire escapes
- Map every ground-floor window and door
- Confirm water plan (still connected, rain collectors, boil/purify)
- Outdoor-only generator pad and fuel path
- Loot distance to tools, food, medical—not “warehouse always has X”
- Basement type: random house vs unique POI lot
- Roof / upper-floor fall protection if you build up
Crafting systems & animals
Blacksmithing & forges
Metalworking is no longer a single vague late-game menu. Expect dedicated forge/furnace/anvil chains, magazines, and skill books. Materials and station names should be taken from current craft data—see Forging the Apocalypse (42.19).
Broader crafting
Pottery, stone tools, brewing ingredients, and expanded weapon crafting support longer self-sufficiency after store loot thins out. Overview: B42 crafting overhaul.
Living animals
Chicken, cow, pig, sheep, deer, rabbit, raccoon, rat, mouse, turkey. Ranch zones and hutches exist as systems; stress, feed, and butchering are full gameplay loops—not flavor text.
What is not a living animal here
Trap/forage carcass items (for example traditional squirrel trap loot) are not the same as a living animal. Do not invent coyotes or other species that are not in the current game definitions.
Lighting, combat, discomfort (high level)
- Lighting — Darkness and light sources matter more for navigation and risk; there is no universal “slider = meter reading” you can trust from a web widget.
- Combat fatigue / discomfort — B42 continues to push slower, more punishing fights and body comfort rules. Treat specific percentage slowdowns only if you verify them in-game for that moodle.
- Skills after death — Still a separate systems topic: keeping skills after death.
Farming months (Build 42.19)
Showing all 32 crops.
| Crop | Sow | Best | Bad | Risk | Growth hours (per stage) |
|---|
Season details that prevent common planting mistakes
- Hops — Not a “summer crop.” Sow Aug–Oct, best September, bad June–July; about 960 growth hours per stage.
- Broccoli — Not “fall only.” Sow Feb–Jul, best March and June, bad September through January.

Character voices (character creation)
Voice styles are named people, not invented timbre tags. Character creation lists every available style with a readable name, then offers pitch and a demo play button.
| Voice style | Notes |
|---|---|
| Bob | Named style in character creation |
| Casey-Jo | Named style in character creation |
| Chris | Named style in character creation |
| Hank | Named style in character creation |
| James | Named style in character creation |
| Janine | Named style in character creation |
| Kate | Named style in character creation |
| Maryanne | Named style in character creation |
- Pitch slider — range −100 to 100, step 1, default 0.
- Demo — play-demo control exists in creation UI; this website does not stream game audio.
- Shouts / exertion sounds — in-world vocalizations still attract attention as before; use them intentionally. Do not rely on a web button for radius numbers.
Fluid system (what is real)
Build 42 treats liquids as first-class contents in containers: transfer actions, mixing in containers, tainted water, fuels, alcohols, animal blood, and more appear across items and world objects. Any fluid mixer view in debug tools is for developers—not a published happiness/thirst formula for fan sites to hardcode.
- Transfer fluids between compatible containers with timed actions.
- Watch for tainted / unsafe water sources (rain collectors, some troughs, environmental fills).
- Do not invent “mix whiskey + juice = +10 happiness” tables unless you verify them in-game for that exact pair.
- Fuel and water contamination mistakes are deadly; label containers in your base.
Discord server options
Server settings group Discord exposes:
| Option | What it does |
|---|---|
| Discord enable | Enable global text chat integration with a Discord channel |
| Bot token | Bot access token |
| Chat channel | Chat channel name |
| Log channel | Logs channel name |
| Command channel | Commands channel name |
Multiplayer & Co-op on Build 42.19
- Host/join with matching Unstable builds; version skew is a common “can’t connect” cause.
- Keep full server backups before every patch day.
- Whitelist + careful admin tooling is safer than open public stress tests for long worlds.
- Server tuning notes: B42 hosting vs B41.
Fishing & trapping
Fishing/trapping continue as viable food lines with deeper B42 rules—see nets, baits, and traps rather than generic “overhaul” blurbs without recipes.
First week on 42.19 Unstable
- Confirm Steam branch is Unstable and note the build version after update
- Fresh save (or accepted wipe) — B41 worlds stay on B41
- Start with zero or minimal mods; re-add only B42-tagged mods one at a time
- Pick voice style + pitch once; do not hunt for non-existent “Deep/Raspy” labels
- Plant only crops whose sow months include your current world month
- Generator outdoors only; never “seal it for stealth”
- If hosting MP: whitelist, backups, and expect patch-day resets
- Prefer in-game tooltips over fan simulators for fluids and traits
