Ok so i did a run thru of The Foundry with my BH and after facing HK47 I got to thinking that it would be awesome to play HK47 having played with him back in KOTOR. Then i got to thinking that being a assassin droid like HK47, Or wardroid like 4X would add a unique experience of the star wars universe from the view of a droid.
This of course is just an idea and i'm not sure how any companions would work but it would definitely be unique
