Make 457 completely die during oxygen depletion

During protocol oxygen depletion, make it where its like if 457 is breached and you do the oxygen depletion protocol, it should be where the entire SCP is destroyed (or respawned) and after that its YE and you cant play 457 for like an hour to add to lore. If you take oxygen away from fire, you cant have fire. It jsut makes sense.
