Ominous Room

Ominous Room is one of the sidequest in Chapter One of Long Gone Days. It can be located inside the Core.

Background
A janitor found a broken key card while on cleaning duty. He doesn't know what to do with it. Rourke can try to figure out what this card is used for.

Walkthrough
Rourke can get the Cracked Card from the janitor inside the Core's cafeteria. He can then have it fixed by the Shooting Range Clerk at the Core's shooting range room (resulting in Rourke obtaining the Elevator Card).

Once Rourke has the Elevator Card, he can use it on the elevator to unlock the bottom floor of the Core. There he will enter a incubator control room, with a window viewing the baby incubators.

In the room, Rourke can obtain a Weapon Upgrade Document from a cache box and obtain the Ominous Room details in his Notes.

After that, Rourke can hand over the Weapon Upgrade Document over to the Shooting Range Clerk in order to exchange his SD-M Sniper Rifle for an Upgraded SD-M Sniper Rifle.
