l'm not sure SuperHero Mod Stats or Forum Mod 1.0 is what l need because of "unofficial" tag - they probably work too but l'm looking for official version if it exist.
https://forums.alliedmods.net/showthread.php?t=76081 this is the official version of SHM. So what is it you are unclear of? The core of SHM is superheromod.sma/amx. The .amx is the complied version of the mod and it is the heart of the mod.
Start with one, once you are comfortable and familiar with SuperHero MOD Stats, then try the Forum MOD if you are able to use it.
