You’ve heard of Last Night on Earth.
ICv2 tells us that it’s the #3 board, card, or family game, if an unqualified statement like that can have any meaning at all.
Actual play, Last Night on Earth style. A ring of zombies closes in and takes down the last hero they needed to kill in order to win.
The game is a scenario-based contest between 1–2 zombie players on one hand and 1–4 hero players on the other. In a given scenario, the heroes might have to kill some quantity of zombies, dynamite their spawning pits, find the keys to the pickup truck and make good their escape, or whatever. There are always four hero characters (at the beginning, anyway), chosen from among eight. All scenarios apply time pressure with a turn countdown that moves toward either dusk or dawn.
As the game plays, zombies spawn and shamble toward the heroes. They can move through walls (that is, up through the floorboards and in through the windows), but advance slowly. They aren’t very good at fighting, but have the strength of numbers on their side.
Meanwhile, the heroes frantically ransack the buildings around the edges of the board looking for cards — items and events — that can help them. Depending on the scenario, once advantageously equipped (or when the zombies press them too grievously), they turn to the game-winning task at hand and sprint for the finish line.
