You have a minor misspelling in the following sentence:

In the end the escapists finally overcome and the ending of the game is them opening the vault door only to decompress the entire vault, killing themselves and everyone else in the process because SUPRISE: the entirety of the game took place on a lunar base designed to reboot the earth after a safe amount of time in the even that emergence day did not go as planned.

It should be surprise instead of suprise.
