Death Road to Canada by Rocketcat Games takes about 15 hours to beat the main story, or roughly 150 hours to complete 100%.
Death Road to Canada is a Permadeath Randomized Road Trip Simulator. You manage a group of survivors through decision making events as you travel from Florida to Ontario, Canada. This is mixed in with exploring, sneaking around, or fighting in randomly generated cities and other locations. Scavenge for supplies, find survivors, and deal with massive hordes of classic-style zombies. Recruit up to four survivors with their own random names, appearances, personalities, and quirks that can both help and hinder your journey to safety. Make your own characters to put in the game, and customize them to be based on whoever you'd like.
