me personally I would go for a bright look completely out of range of era completely sci-fi but in a colorful way. My plan B is to add at least 18 guns! Look at era, they have at least 109 guns total after all these years, but look at izone we only have like 20 different guns and the only guns people REALLY use is rippers and rail gun. Each gun would serve as something a player would most enjoy out of. For example, if someone wants a really fast gun that gun should have a fast speed but something negative along it like low capacity. Also they should be a lot more futuristic look at all the new guns they have the same base color with nothing special about them and they don't match the kind of futuristic that zone was going for at first. It takes a lot to make guns but they usually come out worth it if it serves a good purpose.
