Eukaryotic.io is a free IOGame. If you've ever thrilled to the idea of becoming a cell and experiencing life on a micro-minimalistic scale, then this is the game for you. This is all about the life of a cell, the dangers and the triumphs that are inherent in a science baqsed MMO game in which you must eat everyone else before they get to you. There are no different modes in this game that you can choose from. Each gaming session offers a different experience depending on your strategy and your experience.  You will become a cell but will you be the powerhouse of the cell or the weak-house of the cell? Only time will tell.
