"We just submitted three downloadable levelpacks for N+ XBLA (one of which is free), we’ll be posting with more details as soon as we get a launch time. In total there will be over 750 new levels! The multiplayer maps in particular (over 300 of them) are a lot better than the ones that came with N+, since we’ve had more time to learn what works. We made sure to include more co-op maps, since they’re apparently quite popular.. these ones are even harder, so start practicing!
There’s also a small bonus in each pack which will remain secret for now.. or will it?!"
