Though intended for release early in the year, Gearbox Software, who had acquired the Duke Nukem IP from 3D Realms in 2010, filed a lawsuit alleging the game was in volation of their copyright. Interceptor and 3D Realms chose to salvage the work done on the game by retooling it into an original IP, which eventually released only on PC as Bombshell (2016).Interceptor Entertainment3D RealmsDeep DownDeep Down was announced in 2013 alongside Capcom's new "Panta Rhei" game engine, designed specifically for the PlayStation 4.

It was going to be a FPS game for Windows, PS4, PS5, Xbox One, Xbox Series X/S and was going to be a free-to-play similar to Fortnite and Apex Legends. In early August 2023, Sega executives publicly called Hyenas' development "challenging", raising the possibility it would be cancelled, and stated they would look at "adjusting" the game's business model, possibly to free-to-play. Its development was halted by Sega on September 28, 2023 along with multiple other unannounced games, due to "lower profitability of the European region".Creative AssemblySegaKilling Bites2016Nex EntertainmentLegacy of Kain: Dead Sun2012Climax StudiosSquare Enix EuropeLego James BondIn 2016, TT Games pitched a new entry in their long running line of Lego games, this time based on the James Bond film franchise.
