Upon exiting the Museum, above you and to your left is one group of thugs and a jammer. Another will be on a rooftop bordering Park Row and Bowery. A third will spawn underground. Scan in Detective Vision and listen for incidental dialogue, then pinpoint the source.

OK, JonoAMano, to maybe clarify my problem, I can not get the main front door to unlock to get into the museum! I found a video, and completely understand about the jammers and verbal hints, I can not get to that point. I am stuck at the main entrance. The decoder will not activate.

Before entering the Museum, first enter the Church in Park Row and start that mission. Then visit the GCPD in Amusement Mile to gain access to the Museum code. If you can't breach the Cyrus Pinkney Institute (Museum), then you didn't track Mr. Freeze's temperature signature as instructed and prompted. Many new players miss these details because they're rushing the game.

You're going to have to play some sequential sections of the game as scripted. Don't rush the game, and pay attention to the incidental dialogue and side mission cues when they unlock. Before getting to the Museum you should have destroyed at least 3 chemical cannisters; had two mystery watcher encounters; inspected a sniper kill site; and found Mr. Freeze's temperature trail. If you stumbled upon this early in the game before being prompted, inspected a mutilated corpse in the Bowery after escaping the Steel Mill and after chasing down a few phone calls Dirty Harry style. All of these will help you rank up more efficiently and round out the game.

You have been more than helpful JonoAMano.!!. Ithink I have it from here..!?!

When you're inside the Museum at some point you'll encounter electrified doors. You can circumvent them as Batman, but be a gentleman anyway and shut off the power for Catwoman's upcoming incursion. You'll see why later. As a matter of fact, don't destroy environmental objects that could provide you a strategic advantage, but do break or blow up or disable any barriers that might directly impede Selina from collecting her trophies. Remember, you're playing as not one but two characters, so think Chivalry.

I have been back to the church etc. Now the green main mission prompter is teeling me to go to the museum for the rescue! I have been going nuts, think I will try to find a way to restart!!! unless ,,,

"Holy I'm a dumb butt Batman!!!!" It was" operator malfunction" all this time. I learned how to open the Fricken scanner. 63 years old and I get fooled by scanner!!! I did find alot of riddler trophys though..Mercy!
