Alas, Killzone 2, you could not compete with... Total War.

Yes, Sony's long-heralded shooter has been knocked from the top spot and down to Number 2 by SEGA's new entry of the real time strategy persuasion, Empire: Total War, after but a single week.

Also new to the Chart is Tom Clancy's HAWX from Ubisoft. The air combat game débuts at Number 4, one spot above Halo Wars, dislodged from Number 2 to Number 5.

There's not a lot of movement elsewhere in the Top 10. The only other game to move more than a single place in the Top 10 is Capcom's Street Fighter IV, which has rolled down from Number 3 to Number 7.

The only other new entry to grace the Top 40 is Nintendo's re-worked-for-Wii GameCube title, Mario Power Tennis. It's served up into the Number 23 spot.
