Dying Light is performing better than Techland's other major zombie series, Dead Island. The original Dead Island which was released in 2011 and sold 1 million copies in its first week (compared to 1.2 million of Dying Light) and 3 million copies in 90 days. Dying Light has eclipsed that mark in half the time,
Techland said.
Dying Light still has to do some work to match Dead Island's long-term haul, however, as that game has shipped more than 5 million copies.
Techland released an infographic with some illuminating numbers to mark Dying Light's sales milestone. One such example is that, players have collected $1,250,000,000,000 (that's $1.25 trillion) worth of in-game cash, which is estimated to be about 16X the net worth of Bill Gates(the world's richest person).
Following Dying Light's debut, Techland has launched a variety of free content and more, which includes additional weapons and outfits, as well as Hard Mode. In addition, Techland plans to release mod tools for the PC edition of Dying Light. The developers also pledged to actively support all versions of the game with more maps, modes, skills, quests, and "other original content" in the future.
