Rushmore

Rushmore is a third-person shooter and hack-and-slash hybrid set in the far future. Aliens are conquering Earth, beginning in the city of New Liberty, and humanity brings four figures from American history into the future to help resist them. You play as the four Presidents depicted on Mount Rushmore, fighting alien hordes with weapons and abilities inspired by American history.

The alien threat

Humanity empowers the four Presidents and their weapons with a mysterious goo derived from the aliens themselves.
