Madfinger's Dead Trigger was undoubtedly one of last year's premier mobile games. It brought forth elements that were previously only seen on consoles: quality graphics, a decent storyline, and gameplay that involved more than throwing birds at a some repurposed Jenga blocks. It was (and still is), a gamer's game.
Like with all popular games, we all expected a sequel. Something more immersive, with better gameplay, more features, a deeper storyline, and the like.
