Obtain the broken shotgun from the locker and replace it with the good one on the wall before the spiky wall crushes you.
When the shotgun on the wall gets picked up the TrapCutscene gets played but also an InteractionWithItemUse gets enabled.

This InteractionWithItemUseShotgun object is what allows the player to use either the broken shotgun or the real one from the inventory to place it on the wall. Either way, the used item is removed from the inventory.

When any of these 2 items is used. The InteractionWithItemUseShotgun gets disabled again and the cutscene TrapStopCutscene gets played, which returns the spiky wall to the original position

Both cutscenes will enable and disable an attack on the object SpikeWall which kills the player on contact.
