GfK Chart-Track held off their weekly U.K. sales charts for Memorial Day, but they are online now. The top two on their PC top 30 chart are new, as Overwatch debuts at number one, just ahead of Total War: WARHAMMER. Overwatch also takes the top spot on the all-platforms chart, knocking Uncharted 4 into the number two position. Here's their summary of the week's activity:

Launched on Tuesday across PS4, Xbox One and PC ‘Overwatch’ shoots straight in at No1.

It is the fastest selling Blizzard title on console with 47% of launch week sales on PS4, 36% on Xbox One and 18% on PC. ‘Uncharted 4: A Thief’s End’ ( -37%) makes way, dropping to No2, but managing to stay ahead of ‘Doom’ (-41%) which also falls one place, down to No3. ‘Homefront: The Revolution’ (-41%) slips from No3 to No4 in its second week of release. Only ¼ of the Top 40 lose sales this week as Half Term bundling and promotions give older titles a boost. At No5, sales of ‘Call of Duty: Black Ops 3’ are up 26% while ‘Ratchet & Clank’ (+114%) bounds back in to the Top 10 thanks to retailer hardware bundling, up from No12 to No6. Previous No1s ‘FIFA 16’ and ‘Tom Clancy’s The Division’ are not left out of the promotions with EA’s blockbuster up 3 places to No7 on the back of a 91% sales increase, while Ubisoft’s ‘The Division’ falls one place to No8 despite a 42% sales jump. ‘Total War: Warhammer’ debuts at No9 ahead of ‘Grand Theft Auto V’ which slides 2 places to No10 despite a 49% sales increase. The only other new title to break in to the Top 40 this week is Activision Blizzard’s ‘TMNT: Mutants in Manhattan’, new at No18.
