Just some ideas: Add farming/harvesting wheat.Sports car.multiplayer survival.Mutant pigs and cows.More survivors.Birds.Camps.Bows.Wife/girlfriend (if added more survivors).Boat.Stealing (pickpocketing and more).Locked doors in houses.Work (NOT quests).
Crafting ideas:Any rifle + sword/knife = Rifle with bayonet.
Wood +wood = Stick.
Stick + stone = Hoe
That's all,press + if you think this game needs these things. ;)
