Turtle Rock Studios

Prior to founding Turtle Rock Studios was founded by Michael Booth. Prior to the company's establishment, Booth, Phil Robb and Chris Ashton worked for Westwood Pacific was impressed by Counter-Strike, which was a popular mod of Half-Life, and decided to join the mod team as a texture artist. Eventually, Seattle-based Valve, the developer of Half-Life, purchased the mod, and Ashton left Westwood to join Valve. Robb and Booth remained at Westwood Studios and worked on ''Command & Conquer: Yuri's Revenge and Command & Conquer: Generals'', but left the company after it was acquired by Electronic Arts, as Robb considered EA's acquisition of Westwood had resulted in the studio losing all its personality. Turtle Rock (2002–2007) Turtle Rock Studios was founded in 2002. The team of about six people had limited resources, so the group set up work space in Booth's garage. The name "Turtle Rock" derived from the name of the neighbourhood where Booth lived. Upon the release of Source, the company wanted to work on a new game, and gained support from Valve. The team decided to use source code from Counter-Strike to develop a mod called Terror-Strike, which is a scenario where players fight against bots, which are equipped only with knives and act like zombies. They also changed the texture of the game to create a gritty, dark atmosphere. It was not conceived as a full-budget project at that time. Meanwhile, the wizard combat game was scrapped as the team considered the project over-complicated and "geeky"; they decided to use the cancelled project as a prototype to work on the zombie game. After being acquired by Valve, Turtle Rock served as Valve's in-house satellite development team, and was renamed Valve South. and that coordination between the two studios was difficult as they were physically far apart from each other. Meanwhile, Turtle Rock felt that the team's communication with Valve was lacking, and it was dissatisfied with Valve and the slow progression of projects. Turtle Rock (2010–2021) After being formally closed, the remaining team members including Ashton and Robb decided to restart Turtle Rock as an independent company on March 17, 2010. On the same day, Turtle Rock Studios put up a new website announcing it had reformed and were once again working on video games. They released an iPhone automotive maintenance app named Garage Buddy and began hiring for a full-scale project. Upon the company's reestablishment, Booth left the company, and Robb and Ashton were requested to share the position of studio head. Ashton initially declined it, but eventually accepted and partnered with Robb to lead the studio. Both of them considered themselves developers not managers, and they found the task of running Turtle Rock a tough challenge. At that time, there were about 13 staff members in the studio. The team later rented a warehouse and re-designed it to accommodate them. The studio was contracted by Valve to work on the post-launch content for Left 4 Dead and its sequel Left 4 Dead 2, which was developed in-house by Valve, and worked on Counter-Strike: Global Offensive during its early phase of development. On September 22, 2010, Digital Development Management announced it was representing Turtle Rock Studios to find publishers for its games. The concept of its next project had begun prior to the development of Left 4 Dead. Inspired by the asymmetrical mode of Left 4 Dead, and hunting games like ''Cabela's Big Game Hunter, the team wanted to create a game where prey could strike back at hunters. The concept eventually became Evolve'', and was the company's next full-scale project. Turtle Rock pitched the game to multiple publishers including Valve. Most of them were not supportive of the idea of an asymmetrical multiplayer video game; Publisher THQ decided to accept the game and help with its funding. THQ's then president Danny Bilson and Jason Rubin were very enthusiastic about the idea of having an asymmetrical multiplayer game like Evolve. Rubin once hoped that Turtle Rock could develop a free-to-play business model for the game. This idea was later scrapped, and resulted in some significant changes in terms of the game's gameplay and cast. On June 10, 2011, THQ described Turtle Rock's next title as "wild". At that time, THQ had already been in a financial crisis that had begun in 2010, and declared bankruptcy on December 19, 2012. Their game, Evolve, was listed, alongside other unannounced titles from: Relic Entertainment, Vigil Games, and THQ Studios Montreal in court documents filed by THQ. With THQ unable to continue its publishing and funding roles, an auction was held for other publishers to acquire these titles. Publishers interested in the game visited Turtle Rock Studio to see its "secret project". According to Turtle Rock, they were "super excited" to work with Take-Two. The game was set to be published under Take-Two's publishing label 2K Games, and was introduced on January 7, 2014 by gaming magazine Game Informer. During the game's development, the team's size expanded to 75 staff members. Originally the game was to be released in October 2014, however 2K later delayed the release date to allow Turtle Rock to further polish the game. Evolve was released worldwide on February 10, 2015, for Microsoft Windows, PlayStation 4, and Xbox One platforms. While Evolve received generally positive reviews, the player base quickly dwindled. The PC version briefly transitioned to become a free-to-play title, but 2K ultimately decided to end the game's support. In December 2016, Turtle Rock announced that the company was working on a new intellectual property to be published by Perfect World Entertainment. The studio would also consider releasing titles via Steam's early access program, which allows players to provide feedback on unfinished games or products as they are being developed. However, Turtle Rock later revealed that the game had been cancelled and that both studios agreed to part ways. The studio focused on creating VR titles from 2016-2019, with noted titles including Face Your Fears 1 + 2, RPG Journey of the Gods and other virtual reality titles, while working with Warner Bros. Interactive Entertainment on Back 4 Blood, a new zombie co-op FPS in the vein of Left 4 Dead, which released for Windows, PlayStation 4, PlayStation 5, Xbox One and Xbox Series X/S on October 12, 2021. As Tencent studio (2021–present) Slamfire Inc., the parent company of Turtle Rock Studios, was acquired by Tencent in December 2021 for undisclosed terms. The studio will remain autonomous under Tencent's ownership. ==List of games==
