Blades vs Guns

While running around with a folding knife playing ninja might be fun a safer tool would be a machete equivalent, axe, shovel, or all out sword. And much more fun. A small knife is a utility and barring no other options the worst to keep from potentially infected scrapes and the slightly more annoying "missing half the neck" syndrome.

Guns have their uses on small crowds where zombie support is minimal or an escape route is open. Though keep something for emergencies, just don't panic. Remember accuracy counts and a Desert Eagle to the cranium is just as effective as a 9 mm. Capacity people!!

Another important thing about guns...They may make a quick kill, but the loud sound will attract hundreds of zombies from miles around. This however can be countered by using a silencer, many of today's guns can be fitted with a noise suppresser that can eliminate the threat of drawing more zombies to your position

Cross bows and Bows are good substitutes for guns. They can be used for long range kills and can be acquired easily at sports shops. They are also silent weapons and will not make as much sound as a gun but for clearing out a huge horde of zombies (100-200) a gun is a better option. Although it should be noted that trying to clear out such a large number of zombies shouldn't be attempted unless you have no other way to get to your destination. It is always best to try to find paths where you can sneak through to your destination, with minimal zombie encounter.
