B42.15 Extinction Sandbox Breakdown (Historical) | Project Zomboid

This page compares the Build 42.15-era Extinction, Apocalypse, Outbreak, and Rising sandbox presets. A/B results below are from that historical snapshot — not current Build 42.19 defaults. Do not copy them into a new 42.19 world without checking the in-game sandbox first.

Known differences on Build 42.19 Extinction versus this snapshot: wound infection factor 0.5 → 1.0, firearm use damage chance true → 2, day/night zombie activity 2 → 1, day length 3 → 4, sound follow distance 100 → 200. Some values still match 42.19 (for example sprinters 6%, respawn 72 hours, firearm noise 1.25), but this page is not a live sandbox authority.
