Gearbox is getting ready for their new DLC character by way of a recent title update that gives your player more pack mule qualities besides the ugly mug and hooves.
The title update will add a host of changes for the game, but the one that's specifically mentioned in the Gearbox forums is the ability for your Vault Hunter to carry around even more equipment, ammo, and the like.
"There will be inventory/backup/storage increases in the update (Free update). More ammo SDU's will be available in the black market along with eridium maximums increased."
More improvements are planned to be added by way of the update. A complete list of changes should arrive later this week, as will a new forum for the new Psycho Bandit character, Krieg.
