Daubed on walls and boards across the island are chalk outlines of a weapon, complete with a glowing color representing the rarity of the weapon; green (Uncommon), blue (Rare), purple (Epic), or Orange (Legendary). The rarity of a Wall Buy increases with the number of Rounds you complete. Wall Buys have a number of uses:
- They allow you to obtain a different weapon type, in case your loadout isn’t doing the job, or you want a secondary Primary weapon.
- A Wall Buy weapon already has a rarity value associated with it (and is therefore more powerful).
- If you’ve defined a Zombie Build, the weapon you purchase will be a rarified version of that customized Weapon or Blueprint, complete with your preferred Attachments and Cosmetics!
