Czech Republic-based Madfinger Games just released a huge update for Dead Trigger 2 on the iTunes App Store and Google Play, just two months after its initial release.

The first person zombie shooter already has over 10 million downloads, and this massive Christmas update, with its new additions and added zombie-killing gadgets, will nearly double the game content for all.

In addition, the Madfinger team has updated the original Dead Trigger with support for new devices so even more folks can join in on the fun.

The Dead Trigger 2 update brings a gorgeous new Chinese environment, with a new single player story and special multiplayer missions set within three regions and 15 different environments. You’ll get to play with 30 different weapons of undead destruction, too, like the new Big Hammer, Brain Mill, Machete, and special Butterfly swords.

There are some limited-time Christmas items for you, as well, available during the holiday, and even more Game Center (Apple) and Play Games (Google) achievements and rewards for playing in global missions.

Madfinger Games is also celebrating Dead Trigger 2’s selection as a Best of 2013 Blockbuster Game in Apple’s App Store by adding one and a half times more gold rewards from December 24 through December 31st, too.

So head on over to the Google Play or App Store version of Dead Trigger 2 to get this free-to-play zombie shooter now. The update itself is free to all current owners of the game, so be sure and update if you’re one of them.
