Nobody's stopping you from downloading their leaked beta.
Sadly it's 1.0b8, 1.0b11 was supposed to fix the 4 (or more? I think there were more... just these I remember) glaring gamestopping bugs in that version (all can be worked around though if you know how). Not to mention fix the horrible mess that the HK Factory is there.
Still got a host of bugs we fixed though, it's by no way less bugfree than TSLRCM 1.6A.
A few nice things they do we don't have:
* A few fighting animations during the Atton/Handmaiden cutscene. As mentioned elsewhere though it doesn't quite work as it should, but it's the thought that matters.
* The G0-T0/Remote cutscene got tweaked so Remote no longer falls through the floor, and Goto now stretches his 'arm' so it appears that he is installing something. That was a nice tweak.
* Entering of the EH (Red Eclipse) looks better with their animated camera. Sadly it's one of the 4 glaring gamestopping bugs though, so make sure you got Kreia in your party when triggering it.
* The "exile is dead" scene leading up to Malachor is nice. Although it follows up to the GenoHaradan on NS scene which is more than meh.
Probably miss some stuff, but this is what comes up in my mind...
EDIT:
And a few dubious decisions they made you have to live with if you do.
* They "fixed" the influence system, making it harder to get INF with teammates. Which pretty much screws over Bao-Dur. And Mira, if they didn't intruce an infinte INF exploit in their conversation (how nice ).
* If you saved your teammates on Malachor this would take away -2 to all stats (STR, DEX, CON) or from one of the stats at random, and lowered saves. Don't recall quite what it was, too long ago. It doesn't really matter too much, seeing how OP the exile is by that point, but I know several people over at the TG forums hated this...
