Gearbox had a Borderlands 3 event recently where they unleashed a lot of information about the new game including gameplay. If you are a super fan of Borderlands the included video is a must watch and includes a showcase of the new Sanctuary starship hub, the first intro level with Claptrap and co-op. It seems that all the guns in Borderlands 3 have alt fire modes where you could have a pistol that fires regular bullets and it's alt fire mode shoots grenades.

Graphically the game looks like Borderlands with a bit more resolution and detail and a higher frame rate. Rand Pitchford boasted that this is the biggest Borderlands game yet, but I didn't get a sense for how big that would be. Hopefully at some point they let us know, but as of now, this looks like a solid follow up to one of the best shooter games around.
