SURVIVE THIS!! Zombies – Ultimate Edition

Your group decides the tone—from bleak street‑level survival to scrappy neighborhood defense—and zooms in on scarcity, noise discipline, barricades, and the fragile webs of trust that keep people alive. The default is contemporary and grounded, but it flexes to rural, urban, or road‑trip play with equal ease.

Theme and Setting

Built on an OSR foundation, the game uses familiar ability scores, classes, and d20 resolution with saves and checks. Combat is fast and lethal; complications from noise and injury escalate quickly.

How Play Feels

Equipment, encumbrance, and ammo tracking matter, but they stay light enough to keep the table moving. Character creation is quick—roll, pick a class, gather a few pieces of gear, and you are ready to face the outbreak in minutes.
