Gigapocalypse (UP)

This is one of the easier “do something to # of items/characters” achievements. In this case, you need to light 10 Fire Beacons on fire. They are found on the ground in Lost Island, and they are quite plentiful, so I played through that world twice and I unlocked this. They look like unlit campfires that will catch when you shoot them, not to be confused with the ones that crumble when you shoot them.
