Let’s face the facts, on any platform pricy is going to happen. It’s just unavoidable. No matter how much security a company puts into securing their product someone will find a way to crack it and distribute by unofficial means. Apparently this has happen to Madfinger games so much for Dead Trigger that the company has decided to make the game free.
Many users have expressed their displeasure with the company after they paid money for the game and most of the fun stuff can only be purchased through in-app purchasing. The game is now free and I recommend you get it from the Google Play Store to limit your chances of getting malware with finding it free elsewhere. The official word from Madfinger can be found below.
Regarding price drop. HERE is our statement. The main reason: piracy rate on Android devices, that was unbelievably high. At first we intend to make this game available for as many people as possible - that's why it was for as little as buck. - It was much less than 8$ for SHADOWGUN but on the other hand we didn't dare to provide it for free, since we hadn't got XP with free-to-play format so far. - However, even for one buck, the piracy rate is soooo giant, that we finally decided to provide DEAD TRIGGER for free. Anyway - DEAD TRIGGER is not FREEMIUM, it always was and still remains FREE-TO-PLAY, that means, all players are able to play it without IAP! We stand up for this statement, because all members of our team are playing (and enjoying) DEAD TRIGGER without IAP.
