- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $1.7k to $2.6k per month (mid $2.2k)
- Opportunity score: $4.6k/month at x2.10 dormancy multiplier

- Studio active elsewhere (2 titles tracked), so this one may welcome a partner
- Last build shipped 4.8 years ago
- Last discounted 1 months ago, 6 sales in the last 12 months
- Proven demand elasticity: x1.7 review velocity during past deep sales

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

|---|---|
| Gross storefront sales | $4.0k |
| After VAT / sales tax (-13% blended) | $3.4k |

## Analyst notes (AI-assisted)

Real-time tactical squad command game where you plan SWAT-style raids and watch them execute with precision.

Door Kickers has quietly accumulated $2.59M lifetime revenue across 603K units on a modest $19.99 price point, with 94% positive reviews and steady $2.18K/mo residual income. The game shows strong elasticity (1.68), suggesting room for monetization innovation or franchise extension. Developer KillHouse remains active, and the core loop (plan-and-execute tactical gameplay) has proven durable; acquisition or publishing partnership could unlock sequel development or live-service expansion.

- Most realistic play: publishing
- Risk (market): Tactical genre has become crowded; without content refresh or sequel, player acquisition costs may rise while residual declines.
- Risk (tech): Game is 10 years old; engine and code maintenance for modern platforms (console, next-gen) could require significant refactor.
- Risk (other): Small studio (2 titles total); limited bandwidth to support aggressive live-ops or simultaneous multi-platform launch.

What players are asking for:
- More single-player campaign levels (explicit in multiple reviews)
- Expansion of mission variety beyond raids and arrests
- Console or mobile versions to reach new audiences
- Procedural or endless-mode content to extend replayability

Suggested first moves:
1. Audit KillHouse's development roadmap and IP ownership; clarify whether a sequel or live-service refresh is already planned or acquirable.
2. Model console (Switch, PS5) and mobile (iOS/Android) ports to project incremental revenue; elasticity of 1.68 suggests price-sensitive audience may re-engage at lower tiers.
3. Commission a 6-month content roadmap (new mission packs, progression systems, social/seasonal hooks) and validate with existing community; $2.18K/mo baseline can likely double with modest investment.

## 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.
