The story about hungry creatures, who are living in the Fog.
The participants of the story were in an unenviable situation. It is unlikely that they would be able to shed light upon the source of abnormal fog. They do not even know what is hidden behind a dense veil. There is a chance to surprise them.
Its some kind of puzzle strategy game, where you play for a creatures against humans.
The player cannot directly control units, but can choose the direction of attack, the number and type/class of attackers.
