"The Journey Down" is a classic point and click adventure game divided in four separate downloadable chapters. The first chapter, "Over the Edge", follows Bwana and his sidekick Kito as they, while struggling to make ends meet, suddenly get thrown into a twisting plot of corruption and adventure.
The Journey Down: Chapter One was based on a low-resolution freeware adventure game, called The Journey Down: Over the Edge. The Journey Down: Chapter One improves on the freeware version with high definition graphics, full voiceovers, plus some additional locations and puzzles. The rest of the chapters will be presented in the high definition style of the commercial remake of Chapter One.
