Demolition

How are you supposed to complete this when the game is essentially over if you fail the first round and everyone backs out? I’ve played at least 15 games of demolition and have yet to win one. My party is filled with bots who are more concerned with kills (obvious bot) and I’m always the only one trying to arm/disarm the bomb. This is the first time I’ve felt like there’s no way I can complete this challenge.
