I think that the single player is amazing. It really brings me back to what I love about Halo. But what I really missed was the hours of joy i got out of system linking with my friends. The multiplayer maps are great and i love that they have been redone and updated, but it is the game play that really matters. WHY IS THERE STILL BLOOM?!?!? why does my pistol not have 12 shots? I really hope to see an update in the near future because if you plan on "staying true" to the original game, we would not be having this conversation.
Edit: I would also like to add that it takes 3 meles to kill someone...are you kidding me?
