Here are some tips for the Batman: Arkham games.

1. You know those annoying armored enemies in Predator? Well, if you got the Remote Electrical Charge, make sure no one is in the vicinity, and blast them with it, then do a Ground Takedown. Plan your escape, though.

2. Use Vantage Points sparingly in NG . If you knock someone out with a Ground Takedown, and then go to a Vantage Point (especially during the Wonder Tower encounter) they will deduce that you are using the Vantage Points. (signified by thugs saying "I see what you're doing! How are you going to use those things if they're not here?!" And the TYGER guards: "Target is moving above us")

3: If there are multiple armored enemies around you, blast them with the REC and focus your attacks on one at a time. (Combat)

1. Be careful with throwing (or shooting) things into the environment. If they are looking at your Vantage Points and you fire a REC round or a Batarang (not Remote Control, unless you press B/O to make it fly like a normal Batarang) they will start shooting at you and destroying the Vantage Points.
