The Empire Staggers Back In the wake of political developments during the summer of 2016 and the events that followed, Britain found itself increasingly isolated from global society.

Assuming command of the near futuristic space ship HMSS Imperialise and her crew YOU will venture into the cosmos, solving puzzles, engaging in witty banter, deal with crippling claustrophobia, gradually succumb to the sustained exposure of cosmic radiation and so on, all for Queen and Country.
