in the game last stand the better way to survive is on the first nights look for survivors. then next when you have novancacy serach for weapons but put 2 hours of looking for survivors,because that way they will die less easily
1.)GET SURVIVORS! 2.)After you have about three, do 6 on survivors and however many you have left after rebuilding your wall on weapons.(Phew! That was a mouthful.) 3.)When you have no vacancy, do two hours on survivors, and the rest on rebuilding & weapons. You should make it through your 20 nights with ease.
