Beginner’s guide

Can you cure a zombie bite?

No. On default settings a bite always infects and the Knox infection always kills.

When does the water shut off?

On default settings, at a random time in the first month. Check a tap; if nothing comes out, it has happened.

What is the best starting town?

Riverside or Rosewood for a calmer start. Muldraugh has more loot and more zombies.

Which game mode should I pick first?

Rising, for a gentler start. Move to Apocalypse, the canon mode, once you can survive two weeks. Avoid Extinction until you are experienced.

Is Build 42 harder than Build 41?

Different. Build 42 adds crafting depth, animals and a much bigger map, and it is now the default version. Build 41 is still playable on the legacy41 branch.

First week

When do the water and power shut off?

On default settings, at a random time in the first month. Check a tap or a light switch; if nothing happens, it is over.

What is the helicopter event?

Early in a run, a helicopter flies over and draws zombies for miles behind it. When you hear it, get inside and stay quiet until it is gone.

Should I clear my whole town in week one?

No. Clear your street and your routes to stores. Fighting more than you need just risks bites and wears out weapons.

Yes, if you find keys and fuel. It carries far more loot and gets you out fast. Just remember engines are loud.
