Hey, thanks for applying, we're always looking for devs.
I know that someone on RZ worked on a custom gunbi server and created those/similar chibi characters with custom animations a few years ago and released them on RZ. Also I think I remember the DBZ character from a release on RZ a few years ago. I'm wondering if you actually created the models you posted or just got your hands on them and reexported/fixed them. Same for the other stuff you said you have, such as Infected and Minecraft quests. I have seen it all in old releases on RZ. Did you actually create it or just downloaded?
That minimap in GunZ was also released on RZ a few years ago, basically it's there by default but disabled. It would require custom minimaps/images for all custom maps (40+) to function properly in custom maps and that's kind of why it's not enabled (and because I don't see much use for it).
