Gearbox Software is hard at work on the third add-on pack for its popular role playing shooter Borderlands. And apparently it’s going to be the “biggest DLC [the developer has] made.”

That’s according to level designer Jason Reiss, who had this to say on the game’s official forums: “After finalizing Zombies DLC, the team and I began reading the DLC feedback around the forums on the wants and desires. Guess what, level cap increase anyone? Got it and it’s awesome.”

“Hopefully we can get a full announcement out to you guys soon but, man is this the biggest DLC we have made. So don’t worry, we are working really hard right now on both the update (that solves a bunch of issues) and the DLC.”

The developer has already released two add-on packs for the game, The Zombie Island of Dr Ned and Mad Moxxi’s Underdome Riot.
