Fuses can be recovered from specific POIs, in Seneca for instance, fuses can be found in the Killjoy Arcade. Once these fuses are removed, they can be inserted in a variety of fuse boxes, enabling Survivors to activate interactable objects, including: doors, the sluice control tower, draw bridges etc.
Out of all of the different types of resources found in Cold Comfort, fuses will more often than not, be the last resource that players tend to focus on. In a world suddenly thrown into chaos, ammunition, medical and building supplies often seem like the logical first choices (and in that order).
Seasoned players will learn to utilize fuses tactically, giving them quite the advantage over unseasoned players.
The corpse nests can quietly and easily be opened by utilizing fuses. Once the corpse nest is opened up, the Survivors can simply render the corpses “unfit for transformation”, thus denying the Gamma Prime players not only that potential Zombie support, but essentially negating a potential respawn.
