The Walking Dead races to 1 million sales

The first episode of Telltale's TV/comic tie-in The Walking Dead has become the studio's fastest selling game ever, hitting the one million mark just three weeks after launch.

That figure includes sales on Mac, PC, PSN and XBLA sales, but not iOS - the portable version is due out later this Summer.

There are four more episodes still to come, with the next, titled Starved for Help, due out some time in June.

"Like the comics, I suspect Telltale's take on The Walking Dead will be something of a slow-burner," read Eurogamer's measured 7/10 The Walking Dead review last month.

"Episode One forces you to make some interesting decisions, and now it's down to the rest of the series to see if they pay off."
