As a new hunter, your life will depend on your fighting skills. The Creach monsters will find you sooner or later and you will have to stand your ground and fight. Over time, you will get a better sense for which weapons are the best fit for your skill set and body type. Until then, I suggest you start with a basic sword and try to master that first. Well, at least get proficient enough that you're not going to get killed by a rat zombie or a mugwump! I'm sorry I can't give you more thorough fighting lessons, but I've included two important clips here to help get you started. If you can learn these two lessons, you'll be on your way to being a better fighter. Heck, you might even last more than a week against the monsters.
PRESSING THE ATTACK
Notice in the first clip that the person on the left launches a strong counter-attack but immediately gets put on the defensive by his more aggressive opponent. He retreats and stays on his heels (as Eva always reminds me, that's my biggest problem.) While it's OK to step back to parry a blow, you must continue to press the attack at the first possibility.
PROPER USE OF A SHIELD If you are lucky enough to have a shield, it can be an essential part of both your defense and your attack. However, you must be careful not to let it lure you into a false sense of security. The clip above shows good form by both fighters at the beginning. See how they both use their shields to block a blow and also to push his opponent in an effort to knock them off balance? It has all the makings of an evenly matched fight until the swordman on the right lifts his shield out of position when raising his sword to strike. This gives his opponent the only openning he needs to finish the fight
