## Analyst notes (AI-assisted)

A 2016 pixel-art strategy game where you command a zombie horde to destroy humanity instead of defending against it.

Zombie Night Terror has generated $607k lifetime on 217k units with a robust 93% positive rating and steady 1.2k/mo residual revenue, despite developer inactivity since mid-2023. The title occupies a genuine niche (reverse-tower-defense with horror comedy tone) and maintains organic player acquisition (17 reviews/mo average). This is not a blockbuster, but a profitable, profitable quiet catalog asset with room for modest marketing lift or a port campaign if publisher rights are clear.

- Most realistic play: publishing
- Risk (market): Low mainstream profile and lack of dev support since late 2023 means no bug fixes, platform updates, or content; player base may gradually age out without intervention.
- Risk (other): High elasticity (1.74) indicates price sensitivity; sustained discounting may erode margins and train buyers to wait for sales.
- Risk (tech): Built in 2016 on legacy tech; compatibility with newer OS versions or storefronts (console ports, mobile) unconfirmed.

What players are asking for:
- Difficulty options or in-game cheat codes to reduce restart friction on hard scenarios
- Meaningful achievements beyond grind and gimmicks
- Balance tweaks to reduce multitasking frustration in mid-stage scenarios

Suggested first moves:
1. Audit IP clearance and rights holder contact for Good Shepherd Entertainment; confirm porting and monetization freedom before investing in platform expansion.
2. Commission a modest post-launch patch (quality-of-life: toggleable difficulty, mid-level checkpoints, achievement rebalance) and coordinate a 2-3 week coordinated discount + community update to signal publisher care.
3. Evaluate console (Switch, PlayStation) or mobile (iOS, Android) viability; 1.2k/mo recurring suggests addressable audience beyond PC who may prefer handheld or touch controls.

## 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.
