- Proven demand elasticity: x2.3 review velocity during past deep sales

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

## Analyst notes (AI-assisted)

Metal Slug XX is a 2D run-and-gun action arcade game, the expanded version of Metal Slug 7 featuring 7 additional missions and classic SNK side-scrolling combat.

Metal Slug XX generates $1,200/mo in residual revenue on a dormant title (no dev updates in 3 months), with 52.7% positive reviews hampered by critical stability issues. The franchise has deep legacy IP value and a loyal core audience, but this specific port needs technical fixes before revival makes financial sense. Acquisition is unlikely unless bundled with broader SNK catalog plays.

- Most realistic play: watch
- Risk (tech): Player reports unplayable crashes before main menu; technical debt on a 5-year-old port may require full QA and patching to unlock dormant revenue potential.
- Risk (market): 52.7% positive score and 11 reviews/mo indicate weak ongoing engagement; franchise nostalgia alone has not sustained player retention on Steam.
- Risk (other): 80% discount active (price $3.99 vs $19.99 list); elasticity of 2.28 suggests aggressive price floors may be masking weak organic demand.

What players are asking for:
- Fix crashing bugs to make the game playable on launch
- Release or port other Metal Slug titles to Steam
- Improve performance on modern systems

Suggested first moves:
1. Audit stability: verify crash scope (OS-specific, driver-related, or localization-linked) and estimate QA cost to ship a 1.x patch.
2. Model recovery: run sensitivity on price vs residual (test $9.99 and $14.99 points given 2.28 elasticity) and forecast monthly uplift from a fix-and-review cycle.
3. Catalog strategy: if SNK considers Steam expansion, bundle XX repair with a roadmap for Metal Slug 5, 6, or mobile ports to build franchise momentum rather than fixing this title in isolation.

## 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.
