Hack the Turret on the upstairs walkway and turn to face the wall. Although they were presumably once covered by semi-priceless works of art, the three wall safes are now fully exposed and waiting to be hacked.
Safe
Contents: 30 Machine Gun Rounds, 6 Film, EVE Hypo
The left-hand safe has moderate hacking difficulty and doesn’t necessarily require an Automatic Hack Tool depending on the number and type of Engineering Tonics you have equipped. Beware that a Houdini Splicer appears in the room as soon as you begin hacking this safe.
Safe
Contents: 6 Armor-Piercing Pistol Rounds, 47 Dollars, First Aid Kit
The center safe is far tougher to hack, and it all but requires an Automatic Hack Tool to open. The contents of the safe aren’t extravagant, but the money is certainly worth the effort.
Safe
Contents: Safe: 2 Dollars, 2 Pistol Rounds, 00 Buck
The safe closest to the Turret is not only the most difficult to hack, but it also has the least valuable contents. If you still have several Automatic Hack Tools handy, go ahead and use one for the sake of being complete, but there is certainly no reason to crack this safe otherwise.
