just remix and add your E-1 variant duplicate the E-1 sprite and change it to your liking. you can use the other vectors or an image to customize your E-1 just don't make the E-1 too big or loud and its fine when you remix change the number by 1 and add the name of your E-1 into the list down there it can be a joke variant you can make the E-1s better if you want current list of E-1s: E-1 XE-1 DG-1 CHA-1 BM-1 EC-1 CR-1 N-1 Unstable-1
i'm sorry i made two if you want you can delete one or just make it never spawn
