The new features are expected to be available in-game sometime within the next six months. "Vehicles will be done based on the architecture we are doing for items/weapons now (i.e. attachments)," Hall wrote. "So it's in progress really. We are replacing the physics system for items (throwing, etc...) and this new middleware will be used for vehicles also."
For those less inclined to murder their fellow humans, Hall also teased more PvE content such as hunting, camping, and base-building. Bases, Hall noted, will take longer to achieve. Barricades are expected to be the first step toward their eventual full implementation.
Hall wrote on Twitter that there will be "experimental" patches for the game regularly, and that updates will be moved to stable status once per month.
