"Tasked with keeping the workers of Jakobs Cove alive, Dr. Ned... does his job a little too well, creating zombies and other abominations that now run rampant in this region," 2K explains, describing it as a "full-fledged expansion." The Zombie Island of Dr. Ned will bring "new enemies, new quests and rare loot drops" for $10 (800 Microsoft Points).
In August, Gearbox CEO Randy Pitchford enthused "People are going to be surprised when they find out how quickly we're coming, and with what content we're coming."
Borderlands will hit Xbox 360 and PlayStation 3 on October 20, with the PC version pushed back until October 26. The Zombie Island of Dr. Ned arrives "later this year."
