1. Make other render for the weapon. Not squares, a small cubes(like on a screenshots from a editor)
2. Secondary and primary weapon. The handgun forever in inventory(ex. Rifle+handgun, SMG+hangun, shotgun+handgun)
3. A 4th weapon - sniper rifle(with a scope) more slowly, but very good optical scope with zoom
4. Map is the two files - vxl map and file with info about spawns(setting spawn areas in vanilla servers)
P.S.: Sorry for my bad english. I hope, you understand me
