Take a look at this novel narrative-driven UE5 game from Liquid Swords studio, which carries strong GTA 4 vibes and features a detailed urban world with a dark, moody atmosphere. The studio is founded by Christopher Sundberg, the creator of the Just Cause franchise.
The game is in development, and there's not much detail about the project. Even the title is undisclosed yet, and the devs refer to it as "#Game1." The studio only shared that the game is "driven by a dark, gritty story that will get under your skin," featuring a strong protagonist and set in an urban open world with "districts that pulse with life" and "streets that breathe."
