Mortal Kombat creator Ed Boon has started posting a countdown on his Twitter feed, leading to speculation the next entry in the gruesome beat 'em up franchise will be revealed imminently.

So far two tweets have been posted: the first asks the square root of 841, which works out as 29. The second asks how many days are in February when it isn't a leap year, which is 28. At this rate, the countdown should expire shortly before E3, around June 2.The most recent project NetherRealm released was Injustice: Gods Among Us, and rumours have been rife that a sequel is on the way . Having said that, it's been around two years since a new Mortal Kombat game was released and 24 star Kiefer Sutherland recently told us he's completed work on a new entry in the series , which hasn't been announced yet.Regardless, whatever it is, there's a good chance we'll be hearing lots more come E3. As soon as we do, we'll let you know.
