Marksmanship:
You need to be able to hit the center of a zombie’s forehead from a reasonable distance if you want to survive.Knife fighting:
There may be a time when you run out of ammo. You should always have a backup weapon(s)!Stick fighting:
This will help you get all the different kinds of blocks down. It will help a *lot* in the long run. It will also help you if you get stuck face to face with a zombie, without *any* weapons. (The only reason I could think of you might be without a weapon was if you were naked and bathing. Even then it would be wise to have some sort of weapon within arms reach!)Lockpicking:
This skill will come in more handy than you think. Useful when you don’t want to smash your way in. Carry your lockpick set with you at all times.Basic Survival Skills:
Most likely there is not going to be power for long after the dead return to life. You need to know how to find clean drinking water and food, how to build a fire (zombies usually don’t like it much), etc.Car Repair:
It would help if you knew at least the basics of car repair. There sure aren’t going to be any shops open to fix your car!
