Postmodern Warfare
First Level
The first level is a flashback level where you are a old man retelling the events of the last level of the game to your grandson. Only your grandson doesn’t exist yet and it’s really you in the present day imagining what it’ll be like to be an old man retelling the last level of the game to your grandson. Then your grandson (who doesn’t exist) kills you.
