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.
