Nooooo!!!
I got to night 20 and then i died. D=
Here's some tips people.
In my opinion, the best combo is this
Hunting Rifle/ chainsaw or the second to last gun you get.
Fully repair every day, and spend half +1 of your remaining hours searching for people until you get to six people. then spend half -2 hours searching.
Usually i spend my day like this.
To start out, - 2 hours repairing
5 hours searching for weapons
5 hours searching for weapons.
Thats the first couple of days. then i go
3- hours repairing
4-5 hours searching
5-6 hours finding people
eventually it ends up like this
1 hour repairing
11 hours searching.
I hope this helped. =)
