In this inaugural video IGN go over Cell Stage, the very first stage in the game. This is when you take control of a microscopic organism and begin your long journey of evolution and advancement. You do this by swimming around your watery environment and eating. If you're playing as a herbivore you're going after algae, but if you're a carnivore you want to feed on plankton and organisms that are somewhat similar to yourself. Of course, the challenge is not to be eaten by things that are bigger than you. It makes for an arcade-style experience that's easy to get into, but that's just the initial way that Spore sinks its claws into you.
As you eat, you gain DNA which can be used to upgrade and evolve your creature. Using the cell editor, you can add or remove parts, and these parts affect your abilities, speed, maneuverability, and more.
