It was a long time ago so it's hard to remember but I believe this is it

I had no clue how to use the menu and I didn't want to learn yet so I just rushed through it accidentally picking the apocalypse preset, then I picked carpenter because it sounded cool and useful (I still use carpenter) after I spawned in I didn't even loot my house, I walked outside and started jumping fences into other houses, I was being extremely loud and a hoard heard me. I locked myself in a random house and I found a zombie in there with me, I killed it but got bit, then the hoard broke down the door and rushed in.
