Ya I made those vids on youtube ... here are all the links to them in somewhat suggested order. What they focus on is making your character, npc team and weapons more powerful. I still suggest to play the game through without glitching once to get a feel for it and to have some kind of challenge, then when you have a feel for the game, plow through it with the mighty powers you can get from the following. ALWAYS SAVE YOUR GAME before trying any of these glitches!!!
skills glitch (give your main character lots of skills and even a high level force power early in the game on Peragus, can be done as soon as you get kreia in your party)
duplicate handmaiden robes (get 99 robes from 10,
)
duplcate items with handmaiden - guns, rifiles, armor, and all the upgrades that can go in them as well as implants, stuff worn on head, shields and arm bands
)
infinite light side or dark side points on dantoine.
dulpicate lightsabers ... nuff said!
super lightsabers! after duplicating, put lots of the same crystal into one saber! stacks for damage related things, not for attribute (ie. wisom) related things
infinite experience in the korriban tomb .. well known but i give hints like 2 hssiss are more dangerous than 20 casue with 20 you can do death field and regain lots of health etc. other strategies
Basically i saw lots of these on gamefaqs and thought, boy, some of what they list here works and some dosent. So, what made sense to me, is to make videos of what does work, and show through a vid how to do it. Im suprised they didnt just do that in the first place, vids are natural learning tools for something so visual as an rpg game like KOTOR 2.
Anyways let me know if you have any comments or suggestions etc. The one with the mines, that's pretty self explanitory there, good idea.
