Each of them at retail

Valve really knows how to craft successful games. After The Orange Box, which bundled together hits like Half Life 2, Team Fortress 2 and Portal, Valve announced that it planned to create a zombie shooter. The game looked so good that pre-orders were 65% bigger than they were for The Orange Box and the title quickly became a hit, both in sales and with critics.

At the Game Developers Conference, which took place last week, the people at Valve gave an update on the sales numbers for Left 4 Dead. The Xbox 360 and the PC version combined sold more than 2.5 million units in the form of boxed copies, which is quite a feat for a game that does not have a single player campaign per se, nor a real story behind the action.

Left 4 Dead is all about taking out hordes of zombies, a few Tanks and, hopefully, no Witches, while fleeing the infected areas for the safety of some mode of transportation.

The game is also sold through the digital distribution platform that Valve is operating, Steam, but the company has a policy of not disclosing the figures for the games sold through it. All we know is that during the weekend, when Left 4 Dead dropped 50% of its price on Steam, sales went up by 3,000 percent, which is quite impressive.

The title is set to get a free expansion pack on April 7, on both the Xbox 360 and the PC. The Survival Pack should add a whole new game mode, which is also to be enjoyed cooperatively, while also making all the campaigns playable in the Versus mode, where one team takes the role of the survivors, the others taking on the role of the infected. The release of the Survival pack will probably lead to another spike in the sales of Left 4 Dead.
