Hot on the heels of its being selected as a Blockbuster Game in Apple’s App Store Best of 2013, Dead Trigger 2 has just received a blockbuster update.

Released a couple of months ago, Dead Trigger 2 is the sequel to Madfinger’s original Dead Trigger first-person shooter. And now, it has been updated with a new Chinese environment, where you can continue the fight for survival amid hordes of zombies in a new single-player story and new warfare missions.

Dead Trigger 2′s latest update is said to nearly double the game’s content as it results in the game’s having three regions, 15 locations, 30 weapons, and more than 150 gampeplays.

And in celebration of the holiday season, Dead Trigger 2 invites you to play in search of limited-time Christmas gifts. The game also presents a system of achievements and challenges, whereby exclusive in-game currency in the form of gold is used as rewards.
