A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Dealernet Returns Dealernet has appeared once again on the terminals across Aneurism. It seems the Midnight Bloc is moving its operations slowly away from the public eye... Version 20 Update With these changes happening throughout the city, work on the new map for Version 20, Genome, will be paused to first fully finish and fix Nightmare, then Misery, including areas we never got to fully explore or furnish. Both maps will be adjusted more toward Nightmare's pacing, as well as finally adding the Mythical Wastelands. Once both maps are on the same footing, work on Genome will resume. But first

If you’re reading this, you’ve probably been very patient waiting for an update… and the good news is: we’ve actually got some good news for you.One year ago, the nightmare began when ANEURISM IV opened its gates to the grand public. What started as a simple passion project slowly spiralled into a full-blown experiment, and after a few… questionable features along the way (think jenkem), it somehow turned into everyone’s favourite life simulator.Anyway, we won’t bore you with the entire history of ANEURISM IV or any of that squishy garbage. We know why you’re here.You want to get back to work.
