Thunder Hammer
How to Get All Weapons in Death’s Door
The Thunder Hammer can be unlocked once you reach the Mushroom Dungeon area. From the entrance to the area in the Hall of Doors, enter Mushroom Dungeon, then head out the main door in this room, in the northeast wall.
Walk across the bridge into the next room, then immediately drop off the right side of the platform you are on. Walk through the door in the corner closest to the screen, then leave the next two rooms through their southeast exits.
Go through the broken stone archway in front of you, then head down the ladder near the wall. Walk down the leftmost staircase, then turn up and cross the bridge.
Continue in this direction until you hit a wall, then turn right and follow this path around.
Climb the ladder, then the staircase, then another ladder, before heading through the exit in the southeast wall.
Immediately turn up and climb the ladder, then follow the path northeast until you hit another ladder. Climb it, go southeast and drop down another ladder, then go through the nearest door.
Walk through this room and through the door, to find a room filled with crates. Smash your way through these crates to unveil a hole that drops down into another area. Jump down into this hole to find the weapon’s location.
