I really, really hope it's not as intrusive as that video makes it look. Halo 4's visual makeup is not my cup of tea. Give me some skyboxes with substance behind them, and not skyboxes that hide the substance of the whole image.

Maybe they'll build contrast by doing different things in different atmospheres? I want to feel stuff like this again.

:/

Showing what appear to be game modes:

The City: Some sort of social hub?
Chapter 3: Singleplayer, probably displaying campaign progress.
Bounty: Unknown, some sort of weekly challenge. 3 stars to indicate different "levels" of challenge / reward?
Strike: This is probably the competitive multiplayer.
Raid: PvE content? The word "raid" implies WoW-style guild raiding to me.
Faction Wars: Unknown, perhaps Guild vs Guild battles or some sort of World vs World?

Edit:
Parties now appear to be called Squads, and can contain up to 6 players.
Each player has a level or rank.
Each player belongs to a Guild / Clan.

The City!

Getting a strong MMO vibe from these shots.

City courtyard close up.

Close up of robotic character with a long rifle.

Forested singleplayer level.

Another shot of same. Unclear how much is playable space and how much is skybox, but it looks as if the level could extend at least to the next hill in the background.

Player character visible in lower foreground.

Edit: could be this level? concept art

Unsure if this is the same level or a different one, but appears to show off 3 player coop.

Also interesting to note the Lobby in the first screenshot only had 3 players in as well. Could be coincidence or perhaps 3 player coop is the max.
Edit: Potentially discredited due to Lobby showing 3/6 players. Possible 6 player coop?

Close up of coop partners.

Edit: Seems to suggest Bungie are sticking to their "carry only two weapons at once" mantra. Both players visible are carrying a Primary weapon and have a Secondary slung on their backs.

What a rip off.

... were not the beautiful art and hints of an amazing universe and series of games - it was just hearing the grizzled ancients like Jason Jones and Joe Staten talk excitedly about a new game. A host of goosebumps overtakes me and I'm instantly transported back to those fun years of anticipation and excitement waiting for Halo 2 and 3.

I'm ready to do it again. :)

I'm just glad I don't have to wait as long as I did for Halo 1

There's nothing sweeter than Bungie talking so excitedly about their new baby. Plus its always nice to see the head unicorn-in-charge at Bungie poke his head out.

I'm ready to do it again. :)

"Shared world" eh?

Is your body ready?

Ralph McQuarrie would be proud. I very much like what I see.

There's definitely a great hint of retro and classic sci-fi influences to temper the newness. :)

Either way, I loved the concept art and gameplay stuff- looks amazing :)
