Game was pretty easy i dont know why people complain about it in the comments. If i had to give any tips id say search everywhere in the easy towns and save aspentown for last it takes to many hours to search and you dont get much. try to give the automatic weapons to the survivors and use traps put them where the survivors are so you can kinda protect them because they die easily. I used the shotgun and attacked the zombies that came running and took my time reloading while there werent any running just walking. Gather as many supplies before aspentown then when you get 9 go to jonestown and just skip directly to union city with 6 supplies left. shoot the head and legs and use the compound bow when you get it with shotgun.
good luck
