Frogwares is a Ukrainian video game development studio headquartered in Kyiv with subsidiary offices in Dublin, Ireland.

[2] The studio released its first open world investigation video game, The Sinking City, inspired by the works of H. P. Lovecraft, in 2019.

With Sherlock Holmes: The Mystery of the Persian Carpet (2008), Frogwares began to develop casual games.

[10] In 2012, Frogwares opened a second subsidiary, 3AM Studios, to release Magrunner: Dark Pulse, a strategic sci-fi shooter based on the magnetization of cubes and platforms to move through each level.

[14][15] In May 2020, Frogwares officially announced Sherlock Holmes: Chapter One, a prequel exploring the early years of the character.

[16] Unlike previous entries in the series, this one would take place in an open world environment, allowing players to freely explore the island of Cordona.

[20] On 24 February 2022, Frogwares posted on social media about the Russian invasion of Ukraine and how it has affected the development team.

The game would be developed from scratch in Unreal Engine 4 and rewritten to serve as a sequel to Sherlock Holmes: Chapter One.

[29] Initially envisioned as a side project, it became the studio's sole focus due to the limiting factors of the war.

Frogware, who remains the sole owner of the rights, had to initiate new certifications and online publishing processes for each individual game to make them available for purchase again.

As a result, Frogwares terminated its contract with Bigben Interactive and removed the game from most online platforms.

[38] In January 2021, the game was restored to stores by court order as the contract was terminated in a 'manifestly unlawful' manner.

[43] On January 2, 2024, Frogwares announced that they became the sole publisher of the game for all platforms, resolving its legal dispute with Nacon.
