It’s easy to put it in MOD, but the original version is a bit difficult. The update of the original version is usually a version update,Of course, the suggestion is very cool. I have also suggested to the official that the bullets of colored ammunition guns can be made into paint, buildings can be painted to change colors, nail guns and oxygen cylinders can be modified into homemade guns with higher damage, but it is difficult for the official to adopt these. If it is a MOD, it will be much easier and can be published in the creative workshop
These features will probably not be used in the vanilla game. But I suggest these ideas so that modders have more freedom and liberty to make cool assets for the game as the modded community is a significant part of Unturned.
