Hard Way:
- Do as much research as possible because it will give you damage bonus
- Save the game as much as possible because enemies are brutal
- Hack every single bot you can
- Use hypnotize bigdaddy and let him do the work.
Easy Way:
- You can start the game on Survivor
- On the light house change the difficulty to easy
- On The end of the mission before you fight Fontain (before entering the elevator), change the difficulty to Survivor.
