State of Decay 2: Juggernaut Edition

Just like it says - if the technician dies during a daybreak session, the achievement will pop. If he doesn't die, that means you won, unless everyone else dies first, but that's pretty unlikely. So basically, losing a session means you get the achievement. Don't heal him, let the zombies swarm him, and you've got it. And if you're going to downvote, be a hero and leave a reason.

When the technician dies it means you lost a match.
So simply after you start the match don't do anything, don't repair the wall and don't shoot any zombies (the achievement will go faster ìf you do nothing). The achievement will pop as soon as the round ends/technician dies.
