IGN writes: "Borderlands isn't much of a mystery anymore. It's a first-person shooter set in an open world with loot drop incentives. You run around environments, do MMO-type quests and murder thousands of enemies so they give you experience points and new guns. When you find a gun you like, you equip it and then use that to kill more stuff. When you level up, you dump more skill points into your character's skill tree to enhance its ability to kill stuff. If you want, you can also play with up to three others for a more social style of murder."
