Project Eden is a 1st person 3D action/adventure game. Rather than controlling a single character, however, the player(s) control an entire squad of characters, and will be free to switch control between them at any time. The game is set in the claustrophobic future city where buildings grow ever-upwards, connected through a thick web of roads, and service channels. Descending through the echelons, conditions steadily decline to slum level and worse, revealing an underworld occupied by criminals, the wretched and deranged. This setting provides a dark and sinister environment with good potential for shocks and horror, as well as a rich source of interesting puzzles and situations.
