DLC 4 is actually happening.
For awhile it seemed like Gearbox was not going to end up doing anything else for our beloved Borderlands, even after the Knoxx twitter account was active again, but today, straight from Pitchford's Twitter, he wrote this:
"I get a LOT of questions about more DLC for Borderlands. Yes, more is coming! T2 already said so! Let's talk soon
"
No other news yet, but this is definitely awesome. Can't wait to see what it is!
Do you think they will make another MODBLOCKER 2000?
Even if they do, they'll find their way...
Ya I heard about this cant wait to see what they will bring to the table. I agree about the mod glitch none of the mods I get from cramerax save...but the thing I hope they somehow add is a more social multiplayer component! Or also an arena besides moxxi that has more variety.
Someone has had a decent look through those files in the v1.31 patch: http://gbxforums.gearboxsoftware.com/showthread.php?t=108873
