Killzone 2 is UK's 4th fastest-selling Sony title, Halo Wars is best-selling console RTS

This past week saw a massive resupply of ammunition for both the Sony and Microsoft fanboys on the treacherous European front of the current console war -- first of all, the highly anticipated Killzone 2 nabbed the top spot in the ELSPA GfK ChartTrack Top 40, and became the fourth fastest-selling Sony-published title ever released in the UK. Its first place finish in the Top 40 charts gave it an edge over number two finisher Halo Wars. You read that right, people. Killzone 2 has become, as many of its zealous acolytes claimed it would, a "Halo killer."

However, the situation isn't exactly grim for said murdered Halo title -- within its launch week, it became the UK's best-selling console RTS to date, beating out former leader Command and Conquer 3: Tiberium Wars by a three-to-one margin. So ... we guess Halo is a "Command and Conquer killer," now? We're not sure. All this inter-franchise homicide is hard to keep track of.
