The New Nuke (It'll be around forever, eh eh eh)

[Anticheese]

Make Security an ineligible place to plant the nuke. A lot of the time there's a ton of apathy towards going in there, since it's easy for a prepared syndicate team to weld/emag several layers of doors shut and get one hell of a head start, AIs are apathetic towards it, and syndicate rounds seem to happen when the server population is low and there aren't any sec officers around that area to begin with.
