This is my first introduction to the series and I love it. Problem solving puzzles are easy enough in the beginning but get really weird after the first chapter though they are simple enough for a noob like myself. They also involve quite a bit of backtracking. Mahjong puzzles are my favorite. The item finding puzzles can get really tough even with the use of sonar (using hints are not needed). Graphics and cutscenes are average but story is fairly well told (typical zombie love story) Some replay value to get the other 50% of achievements
