When Batman confronts the Psychiatrist, He was killed by Ra's Al Ghul who was Hugo Strange master. When Strange is about to die he activates Protocol 11 in whihc destroys the office of Wonder Tower.Thus, forcing Batman to flew the building with Ra's. After Batman landed, we heard and witnessed in the game itself that there are still TYGER forces in the game particulary the helicopters.

> TYGER Command Center: All air units report in,Cease attack and return to base immediately.Repeat,return to base immediately.

**So what happened to the TYGER guards particulary those who are in the helicopter?**

*Follow-up question:* Why didn't they attacked Batman afterwards? Considering that the Dark Knight is their target. Most likely they find out that Batman killed their Boss,Hugo Strange .But they didn't know the truth that Ra's Al Ghul killed Hugo Strange.
