When they talk about the limited editions they keep on saying "this edition includes three exclusive maps". Could someone tell me what they mean by that exactly?

I don't know, maybe like the Arkham Asylum Challenge Maps?

They are linear side-levels, something in the veins of the inFamous sewage levels.

The really bogus thing is that these "maps" aren't DLC. They aren't even some small 4 KB unlock download. They just straight up unlock areas that are already and the disc, and it looks like there are at least four or five of these that you can get from various places including the ones included in the box and this one that appears to only be available by using UbiSoft's lame UPlay program.
