How to Get East Wing Keycard in Rhodes Hill: Walkthrough

Proceed through the West Wing Hall and enter the Kitchen.

Wait for the Chef to move to a new chopping spot, then move the washing trolley behind him. Allow him to get angry and launch the trolley, clearing the path. Hide outside the kitchen door until he calms down, then proceed into the new hallway.

Deal with the lightswitch zombie in the hallway by turning on the light at the far end, near the bathrooms, and sneaking past. Hide behind the cover to the right of the room's entrance after activating the light.

Continue to the shortcut back, passing the Dining Hall, which leads to a stairwell. Climb this stairwell to reach the balcony and then the Chairman's Office. You may encounter a zombie walking past a table; hide in the Filing Room to avoid it.

Climb the staircase to the balcony where the singing was heard. There is a zombie on the stairs; you can kill it or lure it to the Filing Room before proceeding.

On the balcony bar area, you'll find a singer zombie and two others. Sneak past them and follow the pathway to the right, which leads to the Chairman's Office.

Inside the Chairman's Office, locate the Unicorn Trinket Box on a desk with a lamp. Examine the back of the box to find an interaction prompt. Interact with it to obtain the Ruby Crystal.

Head around the corner and unlock the shortcut to the main area with the stairs and the Security Safe Room. Be aware of a patrolling zombie; you can use an Injector on her or conserve ammo. Alternatively, lure her into the Chairman's Office and shut the door.

Return to the lower level of the West Wing and approach the locked door near the Kitchen.

Be aware that the Chef now patrols the corridor between the shortcut and the Dining Hall/Kitchen doors. You can kill the Chef (easier with a Hemolytic Injector, found in the East Wing) or wait for him to pass the shortcut door and run to the Parlor.

With the Chef dealt with or avoided, use the Ruby Crystal on the locked door in the hallway. This unlocks the Parlor, which contains a room for spending Antique Coins on upgrades for Grace. At the back of the Parlor, near a scientist's corpse, you will find a severed hand containing the East Wing Keycard.
