# The Last Disease Z

> ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title.

**Measured on 2026-08-30 03:35 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

- Steam appid: 1843400
- Developer: Bublig
- Released: 2026 · Genre: Action · List price: $8.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $4.5k to $6.8k per month (mid $5.7k)
- Opportunity score: $7.3k/month at x1.30 dormancy multiplier
- Est. lifetime owners: 3.0k · Est. lifetime net revenue: $8.9k
- Review sentiment: 57% positive across 75 reviews (74 from Steam purchases)
- Review velocity: 75.0 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 0 months ago
- Last build shipped 0 months ago
- Store page localized in only 2 language(s)

## Where a gross dollar goes (monthly, at current velocity)

| Stage | USD/month |
|---|---|
| Gross storefront sales | $10.3k |
| After VAT / sales tax (-13% blended) | $8.9k |
| After refunds (-9.5% median) | $8.1k |
| Net to developer (after Steam 30%) | $5.7k |

## Estimated acquisition range

$135.6k to $271.2k (2-4x the trailing net annuity of $67.8k/year). Same error range applies.

## Markets by review language

- spanish: 4% (game NOT localized in this language)
- japanese: 3% (game NOT localized in this language)
- brazilian: 3% (game NOT localized in this language)
- french: 3% (game NOT localized in this language)
- german: 9% (game NOT localized in this language)
- english: 39%
- koreana: 1% (game NOT localized in this language)
- russian: 39%

Localization gap: 23% of measured reviews are written in languages the game does not support (top: german). Localizing is likely immediate market expansion.

## Analyst notes (AI-assisted)

_Note written 2026-08-28 from that day's data; the figures in the header are live and supersede any numbers here._

The Last Disease Z is an early-access survival-crafting game with zombies, base building, and cooperative multiplayer set in a low-poly open world.

This title sits in a crowded survival-crafting niche dominated by established franchises (DayZ, Rust), yet maintains modest residual revenue with a small but engaged core audience. The polarized review sentiment reflects typical EA growing pains: core systems work, but content density, balance, and UX need substantial iteration before it can compete for mainstream attention. Most relevant for publishers seeking a dormant catalog title with low upside but stable margins, or for a developer evaluating technical debt and player feedback loops on a shoestring budget.

- Most realistic play: watch
- Risk (market): Survival-crafting genre is saturated; differentiation versus DayZ, Rust, and Valheim is minimal and not yet evident to players.
- Risk (tech): Persistent reports of UI clutter, audio imbalance, balance tuning (9000 HP boss vs 12 damage axe), and save-file corruption suggest architectural debt.
- Risk (other): Heavy reliance on community guidance (hidden crafting recipes, remote map resources) indicates poor onboarding and world design communication.

What players are asking for:
- Clearer UI/inventory workflow and reduced toolbar friction
- Higher and more varied mob/animal spawn density, especially near starting zone
- Balance tuning: boss HP, weapon damage, loot progression pacing
- Audio normalization, especially for storm/ambient sounds

Suggested first moves:
1. Audit the live figures above against the developer's 6-month roadmap: prioritize whether design debt (UI, balance, spawn logic) or content gaps (POI population, crafting transparency) block retention most.
2. If considering acquisition, request telemetry on abandonment rates by playtime cohort and save corruption frequency; early churn suggests onboarding failure, not just feature incompleteness.
3. Engage the developer on localization (German gap ~23%) and review velocity (70/mo suggests active iteration): clarify whether current trajectory is toward a 1.0 release or a long-tail experimental title.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier, 40-75x by year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by developers; older ones follow the published Boxleiter tables. Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
