OK I wrote this a long time ago for amx and thought I lost the source, but I guess I didn't.
admin command is amx_kafun, it requires ADMIN_LEVEL_H in order to use.
Description
Basically it displays a menu that looks like the weapons restriction menu and you are able to select which weapons players will get each round. Also has an infinite grenade option. Note: Late spawners will also get the weapons that are in the on position. You can disable the plugin by setting sw_kafun to 0.
Note: You can actually give everyone EVERY item in the game, only thing is if there are like 32 players in the server you are taking a chance of a crash. I set it up so every .1 seconds it gives each player the correct weapons (better than doing it all at once which would pretty much guarantee a crash).
