Simmons Family Crest Piece B

2-1, gallows room: as you enter, the chest (purple light) drops down a hole. To open the trapdoor, slide the lever along its track to the right (twice) until it sits under the closest body, then shoot that body's clasp: the corpse's weight holds the lever down. Drop in and open the chest.

Second piece of the crypt crest.

Leaving starts the electric-chair circuit: push the 2 chairs onto their metal plates and knock the zombie that drops in onto the 3rd plate (shoot or punch it while it stands on it; walking over it does not count). The door opens.
