When choosing the weapon layout for a class there are 3 panes. 1 primary wep, 2 secondary wep, 3 misc.
On the 3rd misc item panel there are normally items like shields and smoke bombs.
With a crossbow man for example the third panel ONLY has a tower shield and a lot of locks.
Do these locks on the third panel mean items exist there that can be unlocked? and if so how do I unlock them?
