Dusky
Succubus
First ask Tara if she knows anything about either the bullet or the code - feels kind of random to find those in a chocolate factory. Then things get rather complicated. [3] is clearly a trap, since it's the obvious way. [2] gets us exactly where we want to be - we're a sharpshooter after all, so we want the height advantage - therefore, don't take that way either, it'll be a trap as well.
Seems like we should search the blocked room for the second bonus mission first.
Thirded!
