The Key 1: Flight From Arcadia
It is set in the future on a distant planet (time unknown as time-scale does not seem to match ours). Your objective is to explore an abandoned colony and uncover The Key to the power source of The Hub, the universe's central power source.
The game consists of numerous rendered stills which are clicked in hotspots to navigate from location to location. Apart from moving from location to location and zooming in and out all interaction with the game is done via many 'panels' which can be accessed in numerous locations. Atmospheric sound-effects and some animations are also included.
Unlike many adventure games this one has no inventory, the whole game is resolved by interacting with panels using information gained from other panels.
