## Analyst notes (AI-assisted)

Earth Defense Force 5 is a third-person arcade shooter where players defend Earth from swarms of giant insects and alien invaders across 100+ missions.

EDF5 has generated $4.8M net lifetime on 374k units at $60 and maintains a 94% positive review score with steady 36 reviews/month, indicating a cult-devoted playerbase that continues to engage nearly seven years post-launch. The game is dormant commercially (no sales velocity tracked in 12m, no discounting strategy) but the franchise remains profitable and defensible; revival candidates should evaluate co-marketing with EDF6, regional re-release campaigns, or console port opportunities where the IP still has room to grow. Not a turnaround play, but a steady earner with untapped marketing upside.

- Most realistic play: publishing
- Risk (market): EDF6 launched in 2022 and may cannibalize EDF5 adoption; buyer must assess franchise-wide positioning before committing to EDF5 revival spend.
- Risk (tech): Engine and art are dated; porting to console or VR would require meaningful modernization investment.
- Risk (other): D3Publisher retains publishing rights; acquiring studio SANDLOT alone does not grant permission to re-market or discount the title without publisher alignment.

What players are asking for:
- Balance pass for underperforming weapons (players report 'some suck')
- Cross-platform progression or co-op expansion
- Console versions or Switch port
- New cosmetics or battle-pass style content

Suggested first moves:
1. Audit D3Publisher contract terms: can EDF5 be discounted, bundled with EDF6, or ported without renegotiation? Clarify post-2022 revenue split and IP licensing constraints.
2. Survey SANDLOT studio on capacity for a limited content drop (cosmetics, balance patch, seasonal event) tied to EDF6 cross-promotion at $50-100k investment; model ROI against $11.5k/mo current residual.
3. Research console port technical scope and addressable market for Switch/PS5 indie ports; EDF's arcade appeal and 36 reviews/mo suggest room for dormant platform expansion outside PC.

## 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.
