Behind the security of barbed wire and guards, your group has taken refuge. It’s one of the safest places you’ve lived since the fall of civilization, and it’s given you a little time to recuperate. You set up a workshop and gather some tools.
With your Wrench No. 1, you build the framework for a mechanical suit of armour. You have dreams that one day you’ll be able to walk safely through gunfire in a wearable tank...and you’re just the post-apocalyptic mechanic to figure it out.
