SCP-079's location in-game is incorrect. The game presumably takes place at Site-19 due to the fact that SCP-173 is contained there, along with tons of other Safe and Euclid SCPs (scp-wiki describes it as the largest site in terms of containment).

However, the SCP-079 page mentions this:
SCP-079 is packed away in a double-locked room in the secured general holding area at Site-15, connected by a 120VAC power cord to a small array of batteries

general holding area at Site-15

Meaning that SCP-079 should be at the other site, not Site-19. Then again, chances are is half the SCPs in game are at the wrong site. Meh.

The game has an explanation for this, something in the game says that almost every other site is broken, so they transported the SCPs to this game's location.

Oh, I remember.

All the other sites were attacked by the chaos insurgency, forcing the foundation to use a third-rate base, which is what the insurgency intended
