[Game definition; you have awoke with no memories of your past. Your memories are scattered throughout an empty city; you must find all fragments of your memory to win the Game.]
That is all the main protagonist "Focus," has to go on. She wakes up in the middle of a wood in a small clearing, with no clue what she was doing, or how she got there. She soon realizes she's not alone. There are other Players too, like her, who have no idea what's going on either. Monsters prowl through the abandoned cityscape, that seem only content with hunting down Players, and "deleting" them from the Game. As the Players' sense of humanity begins to blur, one thing becomes painfully clear to her; you'll have to be very careful with who you entrust your life to in this dangerous scavenger hunt. Focus doesn't want to take any chances, but how far will she get with all the other Players that are out for themselves? It's a gamble, with your own life as a betting piece, when you ask; Who can you trust?
