Hi. Yes, barrier art mods do exist, however, due to the concern of importing inappropriate imagery into gimkit, they aren’t available for public use. Sorry.
There’s only two people who have ever even written barrier art mods, and neither of them develop hacked clients. Even gimkit’s largest hacked client developer recognizes the dangers of image importing so you won’t find one anywhere.
Also flexing that you know a lot of gimkit hacks isn’t the best thing to do on the gimkit forums…
