Evaluation

Scam Center Simulator: UnderKingdom launched into Early Access on May 29, 2026, developed by a single solo developer. Since launch, the developer has maintained a rapid and consistent update cadence: major updates shipped on August 1, 2026 (v0.2.0, organ trading gameplay loop), August 17, 2026 (v0.2.1, the Disco Update), and September 17, 2026 (v0.2.4, cat adoption, robot vacuum, and various improvements). Feature patches and bug fixes have filled the gaps throughout. In the September 17, 2026 update post, the developer explicitly states that the next update will be "the final major update before the full release update," promising new areas and additional content. This confirms at least one more major content milestone before 1.0 launch. The developer also announced plans to shut down the standalone Prologue, noting that as a solo developer, maintaining both is no longer feasible — this signals a sharpened focus on completing and releasing the full game. The developer has been highly communicative throughout Early Access, posting regularly and previewing upcoming content in each update. The full 1.0 release remains ahead, with one more major content update explicitly promised before it arrives.

Evidence

About this game

Scam Centre Simulator: Under Kingdom is a darkly humorous management simulation game.

Burdened with massive debt, you are invited to a mysterious town to build your own underground scam empire. Manage your scam compound, abduct tourists for labor, gather essential resources like electricity and food, and trade with the mayor, police, and locals. Will you rise to rule the Under Kingdom, or be consumed by chaos?

Use a variety of scam tactics to generate profit, from theft, phishing emails, and manipulating dating apps, to running online casinos and even cheating at the gambling table. Upgrade your equipment and turn every deception into flowing profit.

Search for individuals with different specialties, cleaners, porters, dealers, and bring them under your control through force. Assign roles strategically, maximize their abilities, and build a highly efficient underground operation.

Manage your scam center and maintain order within the compound. Monitor your workers’ physical and mental condition, and maintain control through punishment or “re-education.”

Upgrade facilities, customize and decorate your base, and expand your criminal empire. Record and customize employee voice lines to enhance immersion and control.
