After several teasers over the last few weeks, Gearbox Software officially revealed Borderlands 3 at Pax East. The first trailer reveals the long-awaited sequel will include over a billion guns (including some with legs), plenty of familiar faces (such as a saxophone-playing Brick and Tiny Tina) and some new characters. It also showcases a number of locations, including a swamp, desert and city full of highrise buildings, as well as plenty of enemies for you to take down.
