Sonic Adventure IV is a Sonic fan game and the latest adventure game.
Eggman is furious. Despite his (self-supposed) IQ of 600, he constantly fails in his schemes to conquer the world, thanks to a super-speedy, talking blue pincushion; taking a lesson from past mistakes, he decides to rebuild the Death Egg using the power of the Chaos Emeralds, but needs help to do it. Making a "brand-new" Chaos E-Series powered by specially created Nega Emeralds (which are highly volatile, take a long time to make, and lose molecular stability when in physical contact), he sends them out to fetch the Emeralds and make his battle station. This (of couse) will not stand for Sonic and friends, who each go out to protect the Emeralds from Eggman's goons.
