# I Walk Among Zombies Vol. 3

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

- Steam appid: 1131550
- Developer: Seacoxx
- Publisher: Sekai Project
- Released: 2020 · Genre: Adventure · List price: $14.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $236 to $354 per month (mid $295)
- Opportunity score: $620/month at x2.10 dormancy multiplier
- Est. lifetime owners: 8.6k · Est. lifetime net revenue: $27.7k
- Review sentiment: 89% positive across 296 reviews (287 from Steam purchases)
- Review velocity: 3.7 reviews/month (6-month average)

## Why it's flagged

- No developer announcement on record, ever
- Studio quiet across its whole catalog
- Last build shipped 5.8 years ago
- Store page localized in only 2 language(s)
- Last discounted 1 months ago, 8 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $536 |
| After VAT / sales tax (-13% blended) | $466 |
| After refunds (-9.5% median) | $422 |
| Net to developer (after Steam 30%) | $295 |

## Monthly review counts, oldest to newest (24 months)

2, 3, 4, 2, 4, 2, 4, 2, 2, 5, 2, 3, 3, 3, 3, 2, 2, 4, 4, 3, 5, 2, 2, 6

## Missed seasonal-sale revenue (modeled)

Skipped 5 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$524 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Estimated acquisition range

$7.1k to $14.2k (2-4x the trailing net annuity of $3.5k/year). Same error range applies.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier (Boxleiter method, 20-75x by year). 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.
