LA Noire has overtaken Brink to become number one in the UK charts, becoming Britain's fastest-selling new IP ever in the process.
Sales of the 40s thriller are beyond that of Red Dead Redemption, Rockstar's last major title.
Platform split is 58 percent on 360 to 42 percent on PS3. For comparison's sake, the split for RDR was 65 percent on 360 to PS3's 35 percent.
The game is now the thirteenth fastest-selling title for 360 and the eleventh fastest-selling game for PS3.
Last week's number one, Splash Damage shooter Brink, moves down two to three this week, with Lego: Pirates of the Caribbean at two.
CD Projekt's The Witcher II: Assassins of Kings enters at fifth following its launch last Tuesday, with Zumba Fitness above it in fourth.
