## Analyst notes (AI-assisted)

Procedurally generated first-person survival horror set aboard a derelict ship, where players must evade an AI monster while locating an escape route.

Monstrum has quietly accumulated 204k units and $790k net lifetime revenue on strong 90.6% positive sentiment, generating $1.9k/mo residually with minimal marketing spend. The procedural generation, high replayability, and engaged modding community position it as a dormant catalog asset ripe for a modest marketing lift or platform expansion; the title's underperformance relative to sentiment suggests distribution and discoverability were the limiter, not product quality.

- Most realistic play: revival
- Risk (market): First-person survival horror is crowded; Amnesia, Phasmophobia, and newer releases have captured mindshare since 2015 launch.
- Risk (tech): Player reviews cite audio fidelity gaps and occasional jankiness; engine or asset refresh may be needed to compete on polish.
- Risk (other): Community is small (20 reviews/mo) but engaged; any revival campaign must avoid alienating existing players with heavy-handed monetization.

What players are asking for:
- Better audio design and enemy footstep clarity
- Additional ship decks or environmental variety
- Official mod support or workshop integration
- Console ports to reach broader audience

Suggested first moves:
1. Audit license and IP status with Team Junkfish; confirm dev appetite for co-marketing or acquisition of publishing rights.
2. Run A/B price and discount testing on Steam (current elasticity 1.27 suggests sensitivity); test $9.99 entry point and seasonal sales to drive volume.
3. Coordinate cross-promotion with Phasmophobia and Devour communities (similar play patterns); explore content creator outreach and Twitch clips strategy to unlock organic discovery.

## 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.
