This is no longer an open-world game. Also, the default gender has changed. You now start in third-person (toggle by pressing tab) in a hub world structure that resembles earlier iterations of the game but replaces vehicular traversal with portal travel.
The hub structure simplifies things a lot and makes the game experience tighter and more focused. It also theoretically allows for gated areas designed specifically for deathmatch multiplayer. This is an experimental feature that, as of the latest update, is turned on for two maps, albeit no competitive or score-keeping features currently exist.
