I would use theblue one because it has a higher SMG percent.

You know I'm right.

If i can get another copy I will hapilly play Horde with you.

I totally agree this was the easiest even on insane.

It's DLC so you need Arkham City.  It's not a full game.

When you see a green henchmen take out everyone but him.  Once you do that hit Y(at least on xbox)to then grab him and find out where certain riddler secrets are.

I get some lag sometimes but most of the time I quit because everyone uses the Sawed off Shotgun.

My favorite map is the Thrashball Arena because of the two areas on the side which my friends and I camp at.

Yeah for me the Sawed off Shotgun is still really overpowered.

I was also wondering that.
