How many days can you survive

[Moogled]

Grab at least one extra weapon in the beginning and then slowly find survivors. Once you have at least 2 survivors, start building your weaponry.

I would recommend the hunting rifle as it KOs nearby zombies and sometimes shoots through others. The chainsaw is unreliable because you can't replenish it.

After a while, I just end up using machine guns to blast them away. Be advised that you lose survivors so try to replenish them once in a while.
