Coming June 25th, Tiny Tina’s Assault on Dragon Keep DLC for Borderlands 2 has you playing a Dungeons & Dragons inspired “Bunkers and Badasses” campaign with Tiny Tina as your “Bunker Master”. She narrates as you play, influencing the action as you go (such as changing it from day to night when it suits her). You can watch the first five minutes in the video up top.
Warning: If you’ve not finished Borderlands 2, the video does spoiler something somewhat. But tastefully.
