Building has not been implemented yet!
Building is an intended feature in Apocalypse Rising 2. Little is known publicly about the status of the feature. Early assets of building supplies were seen in screenshots before the game's initial alpha release, but there has been minimal reference of them since. Whether the building mechanics will take after Apocalypse Rising 1, or are intended to be more unique, is unknown. It is anticipated that base building will be one of the final major features before the game's full release.
