it is possible to survive or not? (Watch_Dogs 2)

No. Manual no saves.

No. Lately, unfortunately, leaves very few games with the ability to save at any point in the game.

ARzamaSec
AutoSave and so quite often and when you exit the game seems to be saving in any case

what I wanted to know

to go to sleep in the shelter

Izi, here is detailed instruction for you:
1. Go to Hackerspace.
2. A little tour of the shelter.
3. A glimpse of the sofa.
4. Approach it and press the action button ( standard E )
5. To set an alarm.
6. Wait until Marcus lay in a stupid position and fell asleep.
7. Wake up from the stupid sound of the alarm clock.
8. The game is preserved!
