Battle Module for Forums

In a php forum i use to visit, they are cfging or installing (dunno), a battle module wich allow you to make an RPG forum w/ online store, to buy guns, clan Admin (To admin your clan and team) and get money system, which gives you 1 coin /each letter in your msgs. The money can be used to buy weapons or clans.

I was wondering if anyone know more about it, if anyone knows of a site which is using battle module.

I saw a PhpNuke forum with something like that, but there were no stores or get money option, you can only get experience and you get to a higher level instead of having a ranking system.

I would like to know more about this. If anyone can help by suggesting a site which uses this. please, I'd thank you.

to be more especific here you go, a link:
