You shouldn't bet on Once Human getting an FPS mode, even if its developer says "elements" might be considered down the line
At least controller support is on the way!
If you're a Once Human fan hoping for an FPS mode, you probably shouldn't as developer Starry Studio has no plans for one.
Like any time a third-person shooter releases, Once Human has some fans that would like a first-person mode, kind of ignoring the fact that when a game is built a particular way, something like that can break it in unexpected ways. As spotted by PCGamesN, an update was shared by Starry Studio responding to some commonly brought up topics, which also included things like character, controls, and the camera. Speaking on the FPS point, Starry wrote, "Including a first-person perspective may result in conflicts with the current game design. In response to your requests, we will consider adding first-person elements into future scenarios and game modes. However, we have no plans to add a first-person perspective to the game at present."
Essentially, don't expect it for the main game, if at all, as again it is a third-person game after all. In more positive news, Starry did also confirm that the 0.3 second delay before your character starts to move is being removed, writing, "The movement windup animation consists of about 20 movements and is quite intricate, so refining some of the details will require some time." It also noted that Vaulting is being upgraded, with a plan to change things so that "the character only begins vaulting after reaching a certain height," as right now you vault and jump at the same time.
Starry mentioned how some fans are discussing cursor delay, though noted that this has already been resolved, and to report the issue if it's still occurring for you, and it also noted that 3D motion sickness and the ability to just press sprint without holding a button can be altered in the game's settings. Lastly, it also reminded everyone that controller support is on the way, set to arrive this August, so those of you holding off picking up the game won't have to wait much longer.
