Seventh Cross Evolution for Dreamcast

Hey microbe boy! Climb out of that primordial ooze and fight for the survival of your brand new species. In Seventh Cross Evolution on Dreamcast, you begin as the planet's most basic, single-celled life form. If you've got the knack for dominance, you progress up the evolutionary ladder and become one of 810,000 species. Along the way, you must fortify your genetic potential by feeding off of vegetable matter or the bodies of your enemies. To evolve, you must gain physical advancements such as intelligence, dexterity, defensive and offensive skills, and healing powers. But most importantly, you must acquire and develop your legs, thus opening up new terrain that your creature can enter. Just like earth's history, this unique game is full of surprises.
