Ultra Rare Key and Map Addons.
These are the only 2 items that don’t have Ultra Rare addons (not counting firecrackers because they have no addons), so I thought I’d spitball a couple of ideas about what they could be.
Key Addons: Keyring- A sturdy metal ring made to hold various keys. With this addon equipped, you will be able to hold another key if it is found in the match. If the original key is used, all addons will be transferred to the second key and the second key will be kept. Escaping with 2 keys will add the extra key to your inventory and whatever addons it might have.
Wax-covered Keychain- This odd keychain has an odd bond with its holder, if a this addon is equipped, the key will not be lost if a survivor dies with the key or uses the hatch. In addition, the key will not fall out of a survivor’s hands unless they drop it manually.
Map Addon: Small Pencil- As you walk around the map you sketch out your path and surroundings. While using a map, press the secondary action key to see where generators, walls, pallets, chests, totems, other survivors, and your path (over the last 10 seconds) are as long as you have passed by it first. This addon causes your map to burn slightly faster.
