You awaken from a cold sleep and suddenly find yourself in the year 2206. What you once knew as the International Space Station is now the International Space Port—a gateway for aliens coming to Earth. Crushed by a massive, unexplained debt, you’re forced into a job you never asked for: Chief Xeno Inspector.

Seems simple enough, just wave in the friendly aliens and turn away the dangerous ones. However, make the wrong call and Earth could be destroyed. No pressure though, right?
