User blog comment:Alb3rtusja/CSO Weapon Restriction/@comment-26990482-20151017073946

I think he meant about restricting specific weapons unlike from the usual weapon class restriction (AWP Only, etc.) such as banning the use of Thanatos-9 in Knife Battles, Balrog-XI in Zombie : Mutant, etc.

But there's a lot of weapons in CSO and would it be possible to be done anyway is something we don't exactly know either. But I agree on this one.
