How did the the Nova6 gas get into the pentagon?

[Spencers132]

On the bottom floor there is Nova6 gas in most rooms i have 3 theorys to how it got there

1. Treyarch are lazy and just copyed the level from the story mode just hoped that nobody would notice

2. After raiding rebirth island they took everything including the test subject to see what they could do and make there own strain of nova gas

3. They found some more of the unstable nova6 gas and tried to change it it a different stain but instaid it turn peple into nova zombies(off topic)

does anyone else have ideas?

Maybe some unknown person attacked the Pentagon?

Just a suggestion :)

I'm pretty sure it's been confirmed that "Five" is to be considered non-canon.

I would have to agree with this, when they say "The Pentagon has been breached" i doubt the President would be there while the Army tried to defend the Pentagon.
