The Hit is a multiplayer stealth-shooter, set in an open-world city with tens of thousands of NPCs. Track down your target and kill them as quickly and cleanly as possible, before the other players can manage it. Try to stay incognito, or photograph other players and take out hits on them.
Here's a gif of my edit objects in action, just slowed down a lot. It's nearly fast enough to generate buildings at runtime, but I'm currently saving out the meshes, which is much faster. At some point, I'll add in an interval system, so buildings can be generated (and regenerated, if part of the building has been destroyed) in the background over several frames.
At the moment, the rooms, doors, windows etc. can only be edited in the Unity editor, but I'll definitely be making versions of these tools for the player, with the eventual aim of having editors and players using the systems in tandem, which will mean games can be written and playtested at the same time.
