Gaming Nexus writes: "A standard video game used to mean that it would offer some gameplay or storyline mode, with the addition of at most a multiplayer option. These days, developers are relying on the extra content and extra modes of gameplay to increase their game's shelf life. As gamers, our response has become to expect this as the standard, particularly for the big-name titles.
If you're interested in the DLC available for Borderlands, you've probably played through the story of the single player game. Maybe you've even picked up The Zombie Island of Dr. Ned for the extra content. Now what? How about an entirely new gameplay mode of battling masses of enemies, round after round?"
