This week, after just three weeks on sale, Madfinger Games' zombie bloodbath Dead Trigger went free-to-play on Android.

In an interview with PocketGamer.biz, Madfinger's sales and marketing manager Anna Porizkova explained that this decision was taken in order to combat a piracy rate of 80 percent.

But this abrupt change to the game's pricing model has angered a portion of Dead Trigger's existing userbase.

These players feel aggrieved that the game they paid a dollar for is now available free of charge, and some of them haven't been shy about venting their anger towards Madfinger.

As console and PC gamers see their game experiences suffer as a result of intrusive DRM and the proliferation of the online pass, it's sad to see a mobile studio come under fire for combating piracy by cutting the price of their game.

But before we get too choked up wondering how a studio could have responded any more magnanimously to the rampant theft of its game, let's move on to our bite-sized overview of the last seven days' worth of news.
