In Dead Island 2, while searching for survivors and supplies, you’re sure to come across fuse boxes missing a fuse preventing you from getting into small rooms or areas containing lots of glorious loot just ripe for the taking. Those fuses can be bought from Carlos at Emma Jaunt’s house in Bel-Air for $1500 a fuse. He normally carries a limited number of them at a time, so make sure to check back frequently and stock up as you go.
