Hydra Bunker

Description
This bunker is used for the main research on the serum. It was funded by the USSR Academy of Sciences, and built by Kuga Heavy Industries. Dr Chandler Tallow used to work here, before the incursion. The bunker seems to be destroyed, since it wasn't present in the Incursion. The big vats imply that the bunker is used for researching the chicken serum, used to make survivrs stronger and bigger. The Update note states that it is the second largest bunker ever built, implying that there will be a bigger bunker in the future. That bunker may be the Core Bunker, because it was the headquarters, or the Fowl Bunker, since Dr Jackson attempted to reach the Fowl when he was in the Egg Bunker to get supplies, making the Fowl Bunker a possible storage for supplies. The Hydra also acted as a temporary storage for the Hatchet Case, until the Hatchet Bunker was finished.

Questions
- We could see a broken Hatchet Case besides the Hatchet Case that was present in the temporary storage. What happened to the other Hatchet Case? Why was it broken?

- There was blood all over the floor. Was this bunker infiltrated? If so, following the first question, why didn’t the person who infiltrated didn’t break both of the Hatchet Cases and only break one?
