Single Player story should be around 10-20 hours like every FPS ever made.
Single Player does have online and offline 4 player co-op through the entire game. Big boon to the game.
Frame rate should be locked @ 30fps at minimum.
The online mode is what makes the game tick and wind up being a great game. It's like a much better version of Goldeneye with everything on it. Tons of modes, no lag whatsoever, voice chat, lobbies, clans, everything that makes a FPS shooter a grand event on multiplayer. Litterally hundreds of millions of hours have been logged on Halo 2's multiplayer mode.
IMO, the biggest thing I'm looking forward to (even though I dislike Halo), is the 4 player on-line co-op through the entire single player game. Gears of War and Earth Defense Force 2017 were so awesome because of 2p co-op. I cannot fathom houw great it'd be with 4 player on Legendary.
Back from the dead, I'm afraid.
