To prevent players to camp inside down basements of New Reno Arms with full teams, which are nearly impossible to assault successfully due to zone loading + unique spawn, lets say that Elridge build a device to kill rats.
Indeed, I suggest to add a switch in the Elridge shop level.
When the switch is activated on surface level, a cooldown of 10 minutes is started. Players who camp the down basement are warned that they have 10 minutes to leave the zone, otherwise, all players in the basement are killed due to gas release.
To bypass this 10-mn fatality, all players have to leave the down basement or to switch down the device on the surface, to interrupt the cooldown.
Same thing for Warehouse (or increase Deathclaws respawn on the down level of the Warehouse).
