Strange New Things is a newly formed game development team composed of industry veterans. They’ve worked on triple A titles including Dying Light, The Witcher, Dead Island, and more. According to their website, they have 144 years in the game development industry combined.
Other than that, not much is known about them. Not who’s involved, not what they’re working on, nothing. Their website is intentionally lacking information, I assume to be revealed at a later date.
