Vigilancer 2099 still exists. The game became known a few years ago, back when it was being developed on Unreal Engine 4.
However, relatively recently Epic unveiled the more modern Unreal Engine 5. Envoidant Studios responded and decided to update the engine for Vigilancer 2099.
Vigilancer 2099 is positioned as an open-world game set in a cyberpunk setting. Players will engage in bounty hunting. The game is inspired by “Blade Runner” and the cancelled Prey 2.
Vigilancer 2099 still has no release date, there is a Steam page.
