I know I'm not the first to discover the pockets of the Old Russia map filled with the near-immortal ?? ranked enemies, but I want to know what other Destiny beta players think about them. I've found two such areas by accident, one going down a staircase and another through a Hive tunnel that exits out of a Tombship. Both scared the -blam!- out of me, yet are a blast to explore and go as far into them as I can.
There's another one by the shores. ?? Fallen Dregs that kill you instantly and won't take shit from your Cydonia AR 3 or Shingen-C. They're blocking a segment of the map that I think Bungie wants to hide from us. I also met another ?? Knight on Skywatch; there's a hidden cave if you keep traveling to the right side of the map. If you "kill" the Knight (by pushing it off the edge), a ?? Ogre spawns.
