Lots of interesting tidbits found in an interview Randy Varnell did with MMORPG.com.
Loot: “Battleborn does feature an extensive gear system, with thousands of procedurally-generated items or various abilities, rarities and strengths.”
Character Unlocking: “A bunch of characters are available at the start of the game, and the others are rapidly unlocked as you play through aspects of the game and complete some early challenges.”
Character Ranks: “Each of the 25 Battleborn has 15 Character ranks for you to achieve”
Technical Test: “You’ll be able to experience a mission from the co-op story mode, as well as play competitive multiplayer for the first time”
