It's... What I expected. Short story (13 missions), lots of collectables, fun webswinging.
But the combat.
Dear god the combat.
You know in Arkham City how the combat was really smooth? This is not like that at all. anyone who has played both of them can probably explain this much better than I can. I can't really explain it but definitely rent it before you buy it if you liked AC's combat. If you played AC you'll see what I mean.
The perspective thing on walls and such isn't a big issue, but don't get this if you are prone to motion sickness. My friend almost vomited when she started swinging around Manhattan. One of the main things that bugs me is how the webs don't actually connect to buildings so there isn't much skill involved in webswinging, but again, that's a small issue.
