# EARTH DEFENSE FORCE 6

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

- Steam appid: 2291060
- Developer: SANDLOT
- Publisher: D3PUBLISHER
- Released: 2024 · Genre: Action · List price: $59.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $15.1k to $22.6k per month (mid $18.9k)
- Opportunity score: $24.5k/month at x1.30 dormancy multiplier
- Est. lifetime owners: 198.1k · Est. lifetime net revenue: $3.5M
- Review sentiment: 70% positive across 7200 reviews (6191 from Steam purchases)
- Review velocity: 43.0 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 10 months ago
- Studio active elsewhere (3 titles tracked), so this one may welcome a partner
- Last build shipped 19 months ago
- Last discounted 0 months ago, 10 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $34.2k |
| After VAT / sales tax (-13% blended) | $29.8k |
| After refunds (-9.5% median) | $26.9k |
| Net to developer (after Steam 30%) | $18.9k |

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

1113, 294, 247, 180, 152, 86, 60, 71, 34, 58, 57, 64, 54, 47, 47, 53, 42, 79, 35, 44, 25, 55, 51, 48

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$70.8k 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

$452.4k to $904.9k (2-4x the trailing net annuity of $226.2k/year). Same error range applies.

## Markets by review language

- french: 1% (game NOT localized in this language)
- english: 69%
- koreana: 2%
- spanish: 1% (game NOT localized in this language)
- german: 1% (game NOT localized in this language)
- russian: 1% (game NOT localized in this language)
- japanese: 16%
- schinese: 8% (game NOT localized in this language)
- brazilian: 0% (game NOT localized in this language)

Localization gap: 12% of measured reviews are written in languages the game does not support (top: schinese). Localizing is likely immediate market expansion.

## Analyst notes (AI-assisted)

Earth Defense Force 6 is a 2024 cooperative action shooter where squads fight alien invasions and giant insects across procedurally-varied missions.

EDF6 is earning $18.8k/mo in residual revenue with strong franchise loyalty (70% positive, 198k lifetime units) and healthy engagement (43 reviews/mo as of late 2024). The title is not dormant: it received a discount just weeks ago and continues selling at full $60 price. However, it faces three structural headwinds: silent Epic Online Service installation (a significant UX/trust liability), upstream design friction between developer intent and long-term player expectations, and uneven localization (Chinese speaker gap at 12%). For a publisher or franchise steward, the opportunity lies in a modest post-launch content push or regional expansion; for an acquirer, the game alone has modest upside without IP ownership.

- Most realistic play: publishing
- Risk (tech): Epic Online Services silently bundle is a documented player friction point that damages trust even among positive reviewers; requires transparent disclosure or removal.
- Risk (market): Low elasticity (0.28) and recent deep sale (59% off, 9 days ago) suggest price-sensitive audience; aggressive discounting may not lift units significantly.
- Risk (other): Developer (SANDLOT) has a pattern of ignoring player-requested feature parity (hardcoded keybinds, no ultrawide support two years post-launch, class rebalancing perceived as backward steps); design philosophy misalignment with enthusiast base.

What players are asking for:
- Keyboard rebinding and ultrawide monitor support (2+ years outstanding)
- Air Raider class rebalance away from drone operator direction
- Transparency on Epic Online Services bundling; opt-out option

Suggested first moves:
1. Audit and remediate Epic Online Services visibility: require opt-in consent or publish technical justification to restore player trust (low-cost, high-perception lift).
2. Negotiate with D3PUBLISHER and SANDLOT for a minor balance patch focused on Air Raider and keyboard/ultrawide parity; position as 'player council response' to unlock goodwill and stabilize reviews.
3. Localize full UI and marketing assets into Simplified Chinese; current 12% gap and 476 Chinese reviews suggest underserved cohort with strong purchasing power in APAC.

Generated 2026-08-20 from public signals and player reviews. Directional, not diligence.

## 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.
