With patch 2.1 it is now possible to fill up the new wall that was added in version 2.0. There are now 11 weapons that can be placed on the wall in addition to the original 19. Changes to the crafting system has made some weapons easier to obtain, as you no longer need certain perks in Technical Ability to craft them.

Some of the weapons can be purchased from Herold the Black Market vendor in Dogtown, but only if you unlocked them while playing and either failed to pick them up or lost them.
