Not sutre if these have been posted but i read a couple more details about the game.
-The graphics engine is built for current
gen but 'scalable' to next
gen platforms, curiously only the PS4 is mentioned directly. I would imagine this would be similar to games of the last
gen like Tomb raider legend, and indeed contemporary (good)
PC-ports, i.e nicer textures and better frame-rate but nothing gameplay changing.
-The multiplayer will take the form of 'crossplay'. The game lobby will take the form of a thirdperson navigated hub called 'The City' where you can meet with your party and show off your gear. From there you can choose to embark on a mission with your party or just go off on your own.
-When you enter a story mission certain parts of the mission will be 'Public combat arenas', the example cited is 'The Dust palace' on mars. Here you will encounter random other players, who you can collaborate with or simply ignore and just carry on with the story mission.
-The customisation is deep. The four main things you can customise are your armour, your gun (customisation appears to be deep, bungie showed slides with 30 different guns based on the same chassis, borderlands was also mentioned during the presentation, as was the word loot

) and finally and most excitingly..... Your SPACE SHIP. Awww yeah!
-The three classes are Warlock (magic, stoopid), Hunter (ranger) and Titan (Master chief) and the four stats are Energy, Shields, Agility and Discipline which apparently Governs your Magic abilities.
-The Enemies are called 'The Fallen' and the three races mentioned are The Vex, who are time travelling robots, The Cabal who are bulky brutes and the 'Space Zombies' who Bungie guaranteed would get a better name once they thought of one.
-The App will allow you to access all the cutomisation options, message friends and have every stat you could possibly think of apparently.
-Finally all the net code and network features during the game are invisible. Similar to the PSN game journey.
