Yep, ur the prehistoric Smilodon, otherwise known as the Saber Toothed Tiger. U were frozen in ice for millions of years, finally found and moved to a museum... still encased in aforementioned ice. One day... one fateful day, the ice shatters and ur free, free to do as u once did - create mayhem and eat everything in sight!
It's ur task in this fast moving action game to eatz and smash everything that happenes to get in ur way. Try not to get killed... u were in ice so long, it would be a terrible waste if u were to die so soon after ur awakening! Right?
