Gambys

Gambys is a 1997 ecological-themed Portuguese puzzle video game for MS-DOS developed by Viagem Interactive. Utilizing 3D pre-rendered graphics for its visuals and cutscenes, it was one of the first fully Portuguese-developed games for IBM PC compatibles. Featuring a story about creatures and man, the game was environmentally themed and featured several photos of animals and scenery in its gameplay

The game centres about an imminent ecological catastrophe created by humans, where the only one capable of saving the planet were small creatures called Gambys. Thought to be a myth, these creatures are revealed to exist. These protectors possess a magical crystal which has memories of what the pure Earth used to be like including animals and plants, and the only way to save the planet is to release these images to the outside world.
