Good review, I'm actually just playing through the ps+ download version before infinite comes out.
Exploring the large levels is fun so far but the story doesn't really grip me. Presenting story bits while the action keeps going is not ideal, and I think I've missed about half of it. I'm not really sure what's going on.
I also keep running out of ammo regularly, especially with the protect the little sister bits. Performance is fine, though a bit low res. The only real bad thing is the unresponsive map.
It's definitely a step below the original Bioshock for me. Hopefully infinite redeems the series. So far it's looking good, at least it will be bright this time.
