Turn a single celled orgasim into the biggest baddest ruler of the universe.
The opening shows you the universe that you'll explore later but to start you zoom down onto the world you choose and start absorbing other lifeforms. Anyone who's played F.L.O.W. will instantly think that there's a serious copyright infridgement here as its basically a copy of that game. SO swimming around attacking other creatures, getting powerups and growing into the next stage of evolution is what you achieving here.
Once you've gained enough experience your onto land to take on the land creatures, then your hunting in packs. You can now explore the land looking for powerups, other forms of life and other things that you'll need later. In the mix is the occassional large beast that'll take a few of your creatures to bring down for essential food. There's plenty to discover here before you move onto the next part of the game.
Now you can bargain or take over other tribes of your species to gain ultimate control over the world. Again plenty of things to fights, build and destroy.
Finally .... Space is big, ITS really big, so big that you can't imagine just how big it is. So now your building spacecraft to move onto other worlds, take creature or brings creatures and plants to make new ones. Populate new worlds and become the ultimate power of the universe.
Everything in the game is moddable, your creature, the vehicles you build, the building and even the ambient music you listen to whilst playing. Graphics are visually stunning and plenty going on to keep you playing til the wee hours of the morning.
Thoroughly enjoyable ... go forth and prosper.
