Wondering what that sign says, but you don't speak the lingo? You might want to figure it out – signs convey important information.

Dead Trigger 2 is certainly one of the prettiest shooters on Android, and it also has one of the highest zombie densities of any game on Android.

The app has gotten three big updates in the last few weeks, including today's jump to 4.1.
