Reus is a game where you control four giant elements - forest, mountain, ocean, and swamp - to shape a planet and its human inhabitants. The giants work together in harmony, with each having unique abilities that bring different plant and animal life, minerals, and upgrades.
The humans will start to settle when food is available, and their growth depends on the benefits provided by the giants within a settlement's borders. However, if the humans become too greedy, they may attack other settlements, prompting the giants to unleash their natural powers of punishment.
