These guys pored over as much of The Force Unleashed as they could stand, then pored over it some more. Then they poured over it, which I don't think I want to get into right now. The end result is an extremely handy "Megaguide" that should help you with everything from those tricky boss fights to finding all of those stupid holocrons so you can finally get that last achievement you've been hunting for.
I'd go back and hunt for that stuff, myself, but Andy just now finished up with the 360 version and now Coonce is going to go for it.
Congratulations to Lies, pyromaniac, and systech for properly exploiting our rad Guide creation tools!
