Weapons stacking is the act of using more than the allotted 2 weapons, i.e. 1 chaos melee and 1 pulse rifle, or 2 swords, or 2 uzi.
The first time you are caught you will be asked to remove offending weapons; a second offense may result in an XP dock. If this becomes a repeat problem with an individual, a much stiffer penalty will be enacted.
* Special Note:
Weapons that do both ranged and melee will count as 2 weapons. You could
have 2 arc gauntlets but nothing else, or 2 gunblades and nothing else;
but you cannot have a gunblade and a different weapon other than a
gunblade.111
