| The First Anniversary Update | 2026-03-13 | 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. And maybe celebrate a little too.Notable changesS |
