The blunt weapons kill slower and the heavy weapons possibly knocks over more zombies but are slooooooow to use. The best melee weapons in the game are the edged weapons. For example: specializing in the 'edged weapon' skill tree will earn you a fighting move that beheads a zombie, a one-hit-kill which takes a little time to perform but is extremely useful. Leveling up your fighting skill with a particular type of weapon will give you the chance to specialize in that weapon. Until you get silencers, they cause more problems than they solve. At least in the beginning of the game, I don't find myself using them much.

TWO melee weapons of your choice in case one starts breaking.

So recognizing when to just leave it be and run away from a fight is essential for survival.

There's no use trying to eradicate all the zombies from the entire map, new ones will always spawn.

Learn to fight, dodge and how to use the killing moves early on.

Always carry medicine with you and try not to let your health get below 50%. Eat some snacks or try finding a safe spot to regain stamina.

When your stamina's depleted you will fight and run MUCH slower.
