So, chalk this up as a rumor until someone receives some verification from Take Two but, GameStop has posted on their website a game guide for Borderlands. The catch is this guide is for the Game of the Year edition.
There is no picture up. There are no details about said guide. There is a release date of September 7, 2010.
The Game of the Year edition would assumed to contain all the DLC. That includes the three packs currently available: Zombie Island of Dr. Ned, Mad Moxxi's Underdome Riot, and The Secret Armory of General Knoxx.
This comes as no surprise since Take Two has reiterated how they will continue to support the game. Here is hoping some more DLC makes an appearance on that disk too.
No one can have too much Moxxi.
