in kotor 3 you should be able to take what ever you want from the corpses like there armour and the light sabers you rarely get light sabers from corpses
kreia shows up in a new body, and she's evil!
no....... some one is in you're body and is evil, no that doesnt go with the game style and stuff that would be cool thow
and I dont think the force can do that, wait if you can get into poeples minds and read theres if you're that power full the you should be able to get in there minds and take over. Shouldn't you?
