Valve's Portal 2 and Warner Bros. Interactive's Mortal Kombat stayed locked in kombat for a second week at the top of the UK software sales chart. Portal 2 maintained its dominance for a second round, but opted not to perform a fatality on Mortal Kombat. Spectators of the tournament included Zumba Fitness, Operation Flashpoint: Red River and Call of Duty: Black Ops in spots three through five, respectively.

The holiday double-whammy in the UK last week (Easter Monday and the Royal Wedding) caused a disturbance in sales. The top ten consisted only of previously released titles, with Just Dance 2 doing the cha-cha back up the charts to re-enter in the 10 spot.

Chart-Track
notes that Sega launched two new titles last week, with Virtua Tennis 4 charting at number 23 and Thor: God of Thunder missing the Top 40 entirely. Check out the usual suspects of chart toppers after the break.
