There are various items in the game that can blind the killer, scavenge the hooks, help repair the generators faster, heal a survivor entirely, and show the location of generators and hatches. These items can either be equipped in your pre-game loadout, via unlocking them in the Bloodweb, or by searching through metal chests found throughout the maps. Numerous Add-ons can also be equipped in your loadout to alter and further enhance the effects of the items.
Note: If the duration of an item is completely used up during a match, or if the survivor dies* with the item, then the player will lose the item.
*Items lost by dying can be picked up by your fellow survivors.
