Sonic Adventure 3

Sonic Adventure 3 (also known as SA3) is a fan-made Sega game available for the GameCube. It is the VERY FIRST (and probably last) of the Sonic games to be based upon the Sonic Archie comics (character and level-wise, at least). It follows the different story mechanisms of Sonic Adventure 2. (Team Hero and Team Dark). It has these Stage types; Running (run to the goal) Escape (much like Amy's stages in SA1, the character doing these stages is usually small and/or cute) Treasure Hunt (find the three whatevers, Master Emerald shards, Chaos Emeralds, etc etc...) Goal Finder (a bit like the Treasure Hunt, but you must find a specific object/area by using logic and puzzles (and sometimes brute force) in order to win (and it takes a while, too, but is really quite fun). However, not all of the teams make use of all categories; the Guard and Arctic stories, for example, have no Treasure Hunt stages, due to the lack of a flying character. This game also makes use of Adventure Fields, like in the first Sonic Adventure.

All of the teams (except for Knothole Team) have six characters. However, three in the Knothole Team (namely Sally, Cream and Amy) must be unlocked first.

Plot
Robotnik's latest plan to take over Mobius may be his most dangerous yet; invoking the power of the vile Lord Serpentius and his Rottid Hordes. Sonic and his friends must not only rally the Knothole Freedom Fighters together, but all the other Freedom Fighter factions as well, in order to combat this demonic menace!
