It's another familiar week of UK cha-... oh wait, it isn't.

After Dead Island: Riptide sliced through its competition for three weeks, this time it's dethroned by another follow-up in the form of Metro: Last Light. By debuting in top spot, it does what Metro 2033 failed to do when it placed fifth in 2010.

Chart-Track says Metro 2033 sold stronger than Last Light in its launch week. Back then, Metro 2033 was fighting March megatons like Final Fantasy 13, God of War 3, and Battlefield Bad Company 2. In contrast, May 2013 has been dead quiet - emphasis on dead.

Having said that, this week sees another new release in the top ten via Pokemon Mystery Dungeon: Gates to Infinity. The spinoff charts fourth this week. We expect the next 3DS Poke-game to do slightly better.

In other movers and shakers, Last Light only nudged Riptide into second place, making this week a 1-2 for Deep Silver and Koch Media. Tomb Raider drops out of the top five for the first time in its 11th week, slipping down to sixth. Meanwhile, Injustice: Gods Among Us and The Walking Dead (packaged retail edition) shuffle into eighth and seventh.
