GM.Name = "Stargate_RolePlay"
GM.Author = "Lece_the_melon_theif"
GM.Email = "[e-mail]"
GM.Website = "N/A"

DeriveGamemode( "Sandbox" )

function GM:Initialize()

self.BaseClass.Initialize( self )

end
--------------------------------------------------------------------------------------------------------------
init

AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )
