Starbreeze has transferred the ongoing support of Payday 2 to Sidetrack Games, allowing the original developers to focus on Payday 3. Payday 2 continues to attract around 30,000 players on Steam, while Payday 3 struggles with about 1,000 players. Sidetrack Games is planning a significant overhaul, migrating the game to a new 64-bit engine called Diesel 3.0, which aims to improve gameplay and reduce file size from 86 GB to 32 GB. An open beta for this upgrade is scheduled to start on June 30 and run until the end of July. The transition will require a complete re-download of the game, and some mods may break due to the engine change.
