With the new equipment swapping feature, you are able to swap equipment between two survivors with just a tap, instead of having to first unequip it from another survivor.

You can swap around equipment between survivors by tapping on the desired weapon. Some equipment may not be swappable, due to one of the survivors being too low level to equip the item.

To help you sort through your equipment, when navigating equipment from the survivor preview, you can see three filters:

Unequipped: Equipment that is not currently in use by any survivors
Equipped: Equipment that is in use by another survivor AND eligible for swapping
Unavailable: Equipment that is in use BUT not eligible for swapping due to the fact that one of the weapons/armors are too high level for one of the survivors
