After seeing this post ( https://www.reddit.com/r/DestinyTheGame/comments/3mdktr/found_the_omnigul_room_in_the_promethean_code/ ) yesterday I wanted to explore a little further to see if could find anything in the room here. Not too much in the Rasputin room itself where you face Omnigul, however I did notice a little doorway on the ground. Glitched out of the map and headed over to check it out and found that it was a room underneath Rasputin and there was a pathway leading to it. Images here: http://imgur.com/a/cDUXj Might be another case on the Heroic version of Promethean Code/Siege of the Warmind that this room opens up and need to do something in here. Or could be completely nothing, just found it interesting and hadn't seen anything about it yet. I tried it on the Hunger Pangs quest line, and normal/240 light version of Promethean Code too. Didn't seem to do anything special in either case. Quick video on how to get there: https://www.youtube.com/watch?v=4X7j_-gA4Rc And as the last post didn't show how to get into Rasputin room on the Promethean Code, here's how: [i]Progress though the Promethean Code mission until you reach Bunker War-4. Kill the Taken Psions and the Centurion, then turn back around into the previous room. Jump onto the containers in the water at the bottom, and then try to jump across to the little platform where there's a ladder leading up. You'll die, and on respawn it will put you inside the Omnigul room/Rasputin area).[/i] Video: https://www.youtube.com/watch?v=zAi5E7HdFf0
