AUDIO DIARY: [A Silent God] - Simon Wales
03 - You have the chance to see a new Big Daddy type - Rumbler - in action. This one uses mini turrets (an alternative ammo type for your [Hack Tool] and fires rockets. Despite the fact that you can try to avoid his attacks and hack his turrets, it's worth to take advantage of the fact that this particular type is quite lousy at close combat. You shouldn't use more than one health pack by equipping the Drill enhanced with proper Tonics and keeping the Daddy at close distance. Take over the first out of three Little Sisters. There's a lot of proper bodies in the area, so choose ones that are easy to defend and use the turrets.
NOTICE: You will receive a gift for rescuing four girls. By the nearest Gatherer's Garden you will find a teddy bear with the [Proud Parent] Tonic, 80 dollars and 80 ADAM.

Now you can return to the Power to the People station and choose an upgrade. It's worth mentioning that the Spear Gun not only effectively nails your enemies to walls, but you can also retrieve the ammo shot from it. Take the Audio Diary from the room to the right (you will find the second one marked on this floor later on, while searching Daniel's body... but he doesn't necessarily have to fall victim to you right here).
