A bit of a switcheroo this week as Dark Void drops out of the top 20 and MAG bunkers down in the top spot, refusing to let anyone get into its heavily fortified foxhole.

Dante's Inferno rises from hell to make a respectable debut at number 2, damning Modern Warfare 2 further down the chart into third while MX vs. ATV Reflex and Madden NFL 10 make their marks on the lower half of the charts.

Borderlands and Ratchet take the biggest tumbles though, both falling seven places to skirt the very bowels of the top 20, while Darksiders is the week's worst performer, falling nine whole placesfrom seventh to sixteenth.

Next week's prediction for number 1? Hmm...BioShock 2, maybe?
