Gears 3 becomes year's biggest launch so far

Gears of War 3 has ended Dead Island's reign of the UK software chart, selling almost as much as the two previous games' launch weeks combined and becoming the seventh biggest 360 launch of all time.

Codemasters F1 2011 takes second spot, pushing Techland's zombie killer down to third.

Zumba Fitness, which occupied the top of the chart for most of the Summer's sparse release period, sees a seven per cent sales increase and moves back up the chart from sixth to fourth place, switching places with Ubisoft's Driver: San Francisco.

Deus Ex retains fifth for a third week, as Warhammer: Space Marine and Resistance 3 both fall two places.
