I apologize for the lack of recent updates At the end of October, I have a big test called a real estate agent I'm so focused on studying that I don't have much time to invest in update I promise you that there will be frequent updates when it is over, regardless of whether you pass the exam or not. Currently, I've implemented low noise, recoil barrel like VSS and multi-barrel like mini-guns. Besides that, I'm going to add various parts to the next update.
