It's going on right now, feel free to join, we need two more. I'll be making regular attempts at the boss so feel free to join in and score some loot.

Edit: This is on the PS4 version.

Played with a Duder today, who played a real good Batman, without him I don't think we would of went on that ten boss victory streak, netting us a ton of diamond boxes. I won't say your name out here in case you don't want your PSN name shared, but I hope you see this. That was great fun.
