Watch Dogs fell 81 per cent week on week, but remains the UK's best-selling video game for a second week running.
The game is Ubisoft's first to hold on for a second week at the top since Ghost Recon: Future Solider back in week 22 of 2012.
Mario Kart 8 is also a non-mover at No.2, sales down 76 per cent week-on-week, meaning Square Enix's Murdered: Soul Suspect must settle for third spot - the game was only 400 units behind Nintendo's racer.
Wolfenstein takes fourth, FIFA 14 is fifth, and 2014 FIFA World Cup Brazil holds at No.6.
NCSoft's Wildstar is new at No.14, one place ahead of 3DS curiosity Tomodachi Life at No.15.
