Invasion

This science-fiction game explores first contact with an alien civilization whose intentions may be hostile. Drawing on stories of extraterrestrial invasion and historical encounters between unequal cultures, it presents the possibility that visitors from another world could act as conquerors, seeking to subjugate or assimilate humanity rather than offering peaceful exchange.
