Battleborn's critical reception may be mixed, but according to Gearbox Software, the game's sales have been "steady" so far. They are so steady that the game is currently doing better than the original Borderlands was doing at this point. Creative director Randy Varnell said the following during a Twitch stream:
"We do a lot of comparisons back to the first Borderlands back in 2009. That launch felt similar to us. Ultimately Borderlands was extremely successful new game for us. Borderlands 1 went on to sell almost 8m units in its lifetime. Battleborn is actually tracking just ahead of where Borderlands was on the sales. We think it’s going to be a game that works like that – a decent, solid launch and we’re seeing steady and growing user counts on all three platforms and we’re hoping that word of mouth is going to take us even further."
That said, the studio isn't getting ahead of themselves as Varnell put it, they are "cautiously optimistic" about the game's release.
