3. Perks
At first, pick your main mêlée weapon and use all your early points into it to increase it as fast as possible, to at least level 3. Your life depends on you being strong enough at smashing zombies with mêlée. The speed of stamina recovery will improve with each point added, and you will probably clear most early POIs using only bow and mêlée - but you don't need points into bow at first. Use any gun as an emergency weapon only, like running into a dog or worse. Hence, the best weapons to focus on, at start, are under strength (clubs and sledgehammers). Other weapons trees are for more seasoned players because strength also have shotguns and tools (miner 69 - mother lode) that are also really helpfull.
