Batman: Arkham City Issue 4

"A Night On the Town"
When Batman attempts to return to Arkham City, he is attacked and cornered by highly-trained TYGER units, meant specifically to match him move-to-move. Nearly defeated, Batman is rescued by Catwoman, who is in Arkham to steal valuables and make strong allies (in this case, Poison Ivy, who she had freed from a prison transport).

Soon afterwards, Batman tracks down and interrogates a TYGER guard, who reveals that Sharp - and, in turn, both Gotham and Arkham City - is controlled by Hugo Strange. Elsewhere in the city, Joker is trying to prolong his inevitable fate by seeing a string of doctors.
