Both protagonists "lying jerks... you're never playing what really happened.
Laura Perusco, Community Lead at Telltale Games, has written up some of the details coming out of the 'Tales from the Borderlands' panel at SXSW. 'Tales from the Borderlands' is of course, the upcoming Telltale Games title set on Pandora after the events of 'Borderlands 2' and its DLC, making 'Tales from the Borderlands' the latest in 'Borderlands' story content.
In 'Tales from the Borderlands,' the player takes on two roles, one for each protagonist, "Rhys, a Hyperion company man with a robotic arm and a knack for hacking; and Fiona, a fast-talking con artist. The story will be told from both of their perspectives, and here’s the twist: both of these characters are lying jerks, so you’re never playing what REALLY happened. It’s more like playing each of their interpretations of events, and the truth lies somewhere in between…"
In addition to playing as tow shifty double dealers, Tales from the Borderlands' is also promising players all of the "crazy, over-the-top action you've come to expect from Borderlands as well, translated into the Telltale style.
