Deep Silver's Metro: Last Light has debuted at No.1 in the UKIE GfK Chart-Track All Formats Top 40.
That means that the publisher has now enjoyed four straight weeks at the top after the three successive crowns won by Dead Island: Riptide, which this week slips to second place.
Last Light wasn't able to beat the week one sales of 2010's Metro 2033, however, although it charted higher – 2033 could only manage fifth place in its first week.
Nintendo's Pokemon Mystery Dungeon: Infinity debuts at No.4, claiming the series' third highest ever week one sales.
