- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $11.3k to $17.0k per month (mid $14.2k)
- Opportunity score: $21.3k/month at x1.50 dormancy multiplier
- Est. lifetime owners: 558.3k · Est. lifetime net revenue: $598.8k
- Review sentiment: 92% positive across 8941 reviews (8589 from Steam purchases)

- Studio active elsewhere (19 titles tracked), so this one may welcome a partner
- Last build shipped 9.3 years ago
- Last discounted 1 months ago, 4 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $25.7k |
| After VAT / sales tax (-13% blended) | $22.4k |
| After refunds (-9.5% median) | $20.3k |
| Net to developer (after Steam 30%) | $14.2k |

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

## Analyst notes (AI-assisted)

A fast-paced arcade shooter with minimalist design and brutal difficulty that earned $599k lifetime and still generates $14.2k/mo in residual revenue.

UBERMOSH is a quiet hit occupying the premium arcade niche: 92% positive, 528 reviews/mo, and steady monthly revenue ($14.2k/mo mid-estimate) despite zero marketing spend and a lone developer. The game's simplicity, high replay value, and 'just-one-more' loop are exactly what survival arcade players want. Opportunity lies in catalog acquisition, licensing for mobile/console ports, or a sequel greenlight; risk is low given established audience, but tech debt and single-dev dependency warrant audit.

- Most realistic play: acquisition
- Risk (other): Solo developer operation; no visible team redundancy or IP management infrastructure.
- Risk (tech): Player reports of crashes and stability issues; codebase may require refactor before porting or major content expansion.
- Risk (market): Extreme difficulty and niche appeal limit mainstream expansion potential; audience is self-selected and small.

What players are asking for:
- Camera/perspective option (first-person or closer view during melee combat)
- Accessibility: invincibility frames or reduced difficulty mode
- Bug fixes and crash stability
- Expanded content variety or new game modes

Suggested first moves:
1. Acquire source code and dev access; commission 2-week code audit to assess stability, refactor scope, and platform-port feasibility (mobile, console).
2. Interview Walter Machado on sequel/expansion vision, IP plans, and willingness to retain involvement post-acquisition or hand off IP cleanly.
3. Analyze top-1% player cohort (100+ hours) for telemetry on engagement drivers; validate whether console/mobile port or sequel would yield 2-3x revenue lift.

## 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.
