Hey:) I have already checked your ME3 walkthrough. Batman AC is not a hard game but there are stuff I have forgotten since I last played Batman AA.
Batman Arkham City Walkthrough
Holy toledo, Batman! Our Batman Arkham City Walkthrough will provide info about gadgets, a storyline guide, and locations of secrets.
Wondrous Hugo Strange
After the fight with the TYGER guards it's time to head up to the top of Wonder Tower to face Strange himself. From the TYGER facility, head into the sewers. You'll emerge back at the elevator where you saved the nurse from Joker's enemies. TYGER guards are all around, so it's time once again to make use of your predator skills. They have night vision goggles but are otherwise the same as every other stealth section encountered up to this point. If you have the upgrade to cancel out night vision this encounter will be even easier.

Once these enemies are eliminated, head up the elevator. Don't wait for it to stop at the top floor, though. Instead use your batcalw to ascend even higher. In the mean time TYGER guards will be setting up an ambush. However, if you used your batclaw to make it to the top, it will be you who gets in the surprise attack. As always, defeat the enemies that have weapons first. If the armored TYGER guard gets his hands on a rifle, be sure to stun him right away. Nothing is worse than a heavily defended foe that can dish out fast damage.

After these guards, it's time to climb the rest of Wonder Tower. This section is very straight forward, though you can use your batclaw to grapple onto ledges if you happen to fall. There are a few TYGER helicopters flying around, but as long as you stay out of their lights you'll be able to ascend unnoticed.

You'll finally locate Hugo Strange, who is guarded by a few more guards. Since they are armed, predator stealth is the safest way to take them out. Hiding in the grates or lurking on the outside ledges is the easiest method for handling these enemies. If you do get noticed, throw down a smoke pellet and get away. You can even hang from the balconies and escape through the lower vents. Check out the above video if you're still having problems.
