BioShock Infinite clings to top spot in this week's UK Charts

Like Booker DeWitt on a skyrail, BioShock Infinite hangs high above the rest in this week's UK charts. Despite a 75 percent sales drop after its launch week, Irrational's clouds-based shooter is numero uno for two weeks in a row. Just below it is Tomb Raider, maintaining its own impressive grip on the UK top two; that's five weeks now it's not budged.

Trion's shooter MMO Defiance marks its debut week by notching third place, and is the only new entry in the top 40. Gears of War: Judgment earns a third week appraisal of sixth, falling behind Luigi's Mansion: Dark Moon in fifth. Meanwhile, Army of Two: The Devil's Cartel and PGA Tour 14 endure second week drops to 15th and 17th respectively.

After just three weeks, Monster Hunter 3 Ultimate is nowhere to be seen in the top 40, although there may be more here than meets the eye. After placing seventh in its debut week, MH3U plummeted to a surprising 37th last week. However, Nintendo of Europe chief Satoru Shibata took to Twitter late last week to apologize "for the current stock shortage" of the Wii U and 3DS game "due to high demand." Shibata said new stock will "hopefully be available" this coming week.
