Today Gearbox acknowledged the next piece of downloadable content coming to Borderlands 2 is indeed named Tiny Tina's Assault on Dragon Keep.
It's coming out on June 25, either for $US9.99 (aka 800 Microsoft points) or for free as part of the Season Pass purchase.
The game centres on narrator Tiny Tina, the rambunctious little teenager who loves to make things go boom. She'll set the scene, which is a board game amongst the vault hunters of the first Borderlands, as you play through her quests. I checked the game out last week and will have impressions and more details for you soon.
