Hello, I'm looking for scenario with zombies, that started in basement hideout with the note of needing to look for more supplies. It continued by travelling to the police station and fighting off zombies.

I don't remember how it continued further. This scenario was very hardware demanding and my pc sucked back then. Now I have a better one and wanna try it, but beside the endless supply of ravage scenarios, I can't find this one

I'd be so grateful if you could help me finding this scenario
