[quote]You know the bit where your guardian is brought back to life? Pretty sure that either in the house of wolves or the taken King that area is now allowed to be explored ( I'm not talking about the plaquelands I'm talking about the original cosmodrome.[/quote] That's not correct. You could always go back to the starting area back in the vanilla game. Outside of the one Ghost that was in the ceiling in the hallway leading back, there wasn't anything there, so people never ventured back there. [quote] In Rise of Iron, the bit where you fight two small waves of hive, with very cool music by the way, ( the last array is the mission ) and the fallen in the strike where you kill omnigul? That's explorable now. With a very easy hive boss too.[/quote] Based on your description (specifically referencing The Last Array) - I can only assume you're talking about the Terrestrial Complex. Nope - it was open in the vanilla game. I had a specific loop to farm spinmetal / patrol beacons that started in the Steepes and looped all the way back to the Divide that had me passing through Skywatch and Terrestrial Complex. [quote]And then the bit where you fight the devil walker in the Sepiks Prime strike ( old one) that's explorable too. Although I'm not too sure if that was already allowed to be explored at the start.[/quote] You're talking about the Blast and that too was open during the vanilla game. A good number of people used that area to do the Fallen Walker bounty in which you had to land the killing shout on a Walker. [quote]And then there's also the bit where you fight one wolf baron and two King barons in house of wolves.[/quote] That's King's Watch and that is only open for specific missions and not accessible in normal patrol. (unless you use the glitch to get inside) TL;DR The only areas that have been added or opened up in the Cosmodrome since the vanilla game is what was added specifically for the Plaguelands and RoI.
