Version two of my earlier mod (http://knightsoftheoldrepublic.filefront.com/file/T3M4_to_HK48;98911), this version differs from the last one, in that "HK" has a new skin and more reasonable stats.
I still haven't been able to change all of the dialogue in-game to refer to him as HK, but maybe next time I'll fix that.
I also changed his soundset (just the battle noises and responses) to that of a Laigrek. The change is hardly noticeable unless you listen for it, but its pretty cool.

I like this.

I'll give it a try on my next playthrough of TSL.

AWESOME! Makes playing T3 worthwhile. Will try this out soon.

Thanks guys. I'll work on getting some better screens up by tomorrow.

nice job keep up
