Seeing as there are no ways at the moment to get any new martial arts styles, since NPC’s are disabled and karate books don’t exist yet, I’ve been using the debug menu to give myself all the martial art styles.
I don’t mean that as I start off with no unarmed skill (I never usually take it) and go around using Lizard Style to wall-kick zeds, or using Taekwondo and spin-kicking cougars in the face, but if I read up to level 3 in unarmed with the 101 Wrasslin’ Moves skill book, I’ll let myself use Judo. This makes sense in terms of realism, since wrestling and Judo are pretty similar (you spend the majority of both throwing and/or being thrown) and this provides a way to actually gain them. Also, if I get my unarmed to 5 I might give myself Krav Maga, or if I get it up to 3 just by falcon-punching dogs I might give myself karate, rather than Judo.
I do this for the sake of role playing. Krav Maga IRL is a very lethal form of martial arts, so it makes sense for someone that was fighting zombies with his bare hands to figure out some form of it. And as was previously mentioned, judo and wrestlin’ are pretty similar. Seeing as there is no other way to get these styles without reactivating NPC’s manually, (and then getting lucky if they know something or not) do you consider this cheating?
