Firesprite has been entrusted with bringing the Horizon franchise to PlayStation VR2 with its new game Call of the Mountain, developed alongside Guerrilla Games. Though there are no details about what the game might actually be like, a former employee at Guerrilla has stated that this will change the game for AAA VR titles. This announcement also confirmed a rumour from Nick Baker last year.
A Twisted Metal remake is also rumoured to be in development. Apparently, Sony was so unhappy with XDEV-partnered Lucid Games that the team were stripped of making the game despite releasing Destruction All-Stars to prepare for it. Instead, Firesprite appears to now have the Twisted Metal project according to some reputable outlets. This now has all been underlined with the hiring of ex-Evolution employee and action-racer Motorstorm director Matt Southern. This game appears to be PS5 only and coincides with the 2023 TV show.
Head of PlayStation Studios, Hermen Hulst, and managing director of Firesprite, Graeme Ankers, confirmed in an interview to GamesIndustry.biz that Firesprite is working on more than one project. One is a massively multiplayer game and the other is a dark narrative experience. A recent job posting was tracked by IGN that confirms the existence of an "ambitious unannounced AAA title," possibly Horizon Call of the Mountain or one of the above projects.
