Make silicons unable to unscrew the nuke

[Boa Jacque]

Never seen or done this, and I don't think its a problem.

But then again I dont know how long the timer goes down for unscrewing it.

Just adjust that variable if its too much. Honestly if the crew can grab the nuke, they've probably won anyway. If not, the round becomes one of those silly comedies where theres an endless goosechase down the hall... until the damn thing goes boom
