You will know which ending you get, trust me. I don't want to spoil any of the story for you, (yes there is a storyline in this game) but after you reach the end of the 72-hour period, there will be a special cutscene.
After you complete the game once, there will be a special gametype to play. This gametype is called Infinity Mode. In this mode, you must survive as long as you can until you die. You health slowly gets depleted as time goes on. Once you die, the game ends, and you will get all the stats. Reaching your 7th day, you will unlock the achievement.
