no i dont belive there is any custom's....
i dont know if sam will add customs as it can be quite dificault and.. will make the server unstables and make it crash and that...
i know that there is a way to add custom's to 562's but like i said it is very dificault
so yeahh idk about that one.
personally i would love to see something new in here but ....
thats just me ... plus makes server lag and crash all the time so yeah i dont think we will have custom's
sorry
