Rocksteady needs you - Hiring Arkham City Tour Guides

[Earthum]

The key to combat is racking up combos. Don't get overwhelmed by your enemies and start button mashing.

[ed_sid]

Keep an eye out for enemies that glow green (in detective mode). If found then save them for last in combat to interrogate them for some riddler trophy locations!

[Tasnek]

Try and think one or two moves ahead in combat.

[rialbetancourt]

Do not panic... after all... YOU ARE BATMAN.

If you're new and are facing a large number of adversaries, use your surroundings to your advantage. Use the grapel to pull yourself out of a conflict quickly, once on your way up to a highpoint, release and divebomb back down knocking the opponents to the ground. Allowing yourself a few takedowns and a breather.

Must see tourist spots:
Use the back door of the Solomon Wayne Courthouse to visit Calander Man (with bonuses if you visit on a holiday - marked on the calander next to his cell).
After defeating Two-Face look up at the roof of the building directly in front of the Courthouse. Have a chat with a local vigilante.
Behind the Monarch Theatre is Crime Alley, the site of the Wayne's murder. Pay your respects to Bruce's parents with roses and pearls.

In the courthouse, notice the impeccable side and the destroyed side in the entire building, wonder who could've caused that....

[MOVIELORD101]

Be sure to use Detective Mode often! They might reveal hidden goodies within Arkham City itself....
