"Intérieur" is an adventure game that is somewhat different from traditional adventure games. More than objects, they are ideas and above all a story that you must discover, a situation that you must understand.
The player pilots a spaceship from a 1st person perspective. The ship automatically warps through hyperspace, and arrives in combat with an enemy vessel. The player has a limited fuel supply, and must quickly destroy enemy vessels. As the player proceeds, they arrive at local starbases, which allow the player to save their progress and earn ranks. The goal is to reach the rank of Commodore.
