Lady Shiva and The Riddler confirmed for Batman: Arkham Origins

IGN has got their hands on the list of Achievements for the upcoming Batman: Arkham Origins game, which reveal a couple of interesting tidbits.

Firstly, and this should surprise nobody, the Riddler is set to return with his ever-popular (slash frustrating as hell) challenges.

But the real news is the reveal of the inclusion of Lady Shiva, who looks set to be the 6th of the 8 assassins to he featured in the game.

“10 G: Flawless Display – Successfully battle Shiva without taking any damage.”

So what do we make of this news, and do we have any predictions for the last two?
