Chart Track reports that THQ's UFC 2009: Undisputed has held onto the No.1 position, despite a 42 per cent drop compared to week one sales.

Nintendo's Pokemon Platinum also holds at No.2, while EA Sports Active saw a 42 per cent increase in sales, but wasn't able to better its No.3 position from last week. Guitar Hero: Metallica is the highest placed new release at No.4, closely followed by PS3 exclusive superhero title, inFamous, at No.5. SEGA's Virtua Tennis 2009 also enters the chart at No.8.

The week's only other Top 40 new entry is Warner's Terminator Salvation, just missing-out on a Top 10 place at No.11.

Look out for strong new entries next week from Red Faction: Guerrilla and The Sims 3, with the likes of Fuel, Star Ocean: The Last Hope and Sacred 2 also looking for chart entries.
