Previews based on Campaign play are starting to appear – we saw two new ones this morning. Both of them looked at the same level (NMPD HQ) – neither contains story spoilers.
IGN’s article (thanks,
DancingJesus) summarizes how gameplay in the campaign actually works, and then discusses the level, with a focus on how gameplay is different between Halo 3 and ODST.
WorthPlaying’s article (Thanks, Adam) focuses more on how the level is laid out, and discusses the voice acting (and AI) of the non-player denizens of this world. (It also has a summary of the new Mythic multiplayer maps.) Go read ’em – and get psyched! ODST drops in 11 days.(Louis Wu 13:01:06 UTC)
