The party will be forced into an hour-long Siege, which takes place in a small suburban area. There are two roads, in the middle of which several skeletons and Supplies can be found; there are also several houses and piles of rubble which the party can use to maneuver around the zombies.
From a distance, the group sees some skeletons and loot in the middle of a debris-blocked street. They walk over to get a closer look. This gets the attention of a horde of zombies that rush out from all sides.
SIEGE ALERT! THERE'S NO ESCAPE!
