Byterunners Game Studio

Byterunners Game Studio is an independent Polish video game developer founded in 2020 by programmer and game designer Rafał Pęcherzewski. Commonly credited as Byterunners, the studio develops simulation and action games, with work spanning first-person systems, crime and economy simulation, and twin-stick shooters. Alongside its own games, it produces game assets and 3D models for third-party developers.

The studio became known through Drug Dealer Simulator, released on Steam in April 2020 with publisher Movie Games. Its development credits also include Drug Dealer Simulator: Free Sample and Drug Dealer Simulator 2, which followed in June 2024 and expanded the series with cooperative play. These projects established simulation games as a central part of the studio's portfolio.

A new development chapter

Following the breakdown of its publishing relationship with Movie Games in 2025 and subsequent disputes, Byterunners moved on from the Drug Dealer Simulator intellectual property. The core development team remained intact and transitioned to a new project with a different genre and publishing partner.

As of October 2026, the studio is developing Raining Lead, an anti-corporate twin-stick action roguelite announced in 2026 and published in partnership with Hyperstrange. The project extends its work from first-person simulation into action-focused game design. Byterunners continues to operate independently from Poland and communicates with players through Discord, Facebook and X.
