It depends what emblem you want. Some ways you can get them are:
Completing levels
Watching the credits after final level of a charcter
Find hidden one in the field
Chao races
Getting A and B in levels
yes, my brother has completed the whole game. To get metal sonic you have to get every single emblem and finsh all the other story modes
if you actually played the game you would know that an emblem is what you get when you complete a level you idiot. don't ask a question that can be answered by simply playing the game
There is a Sonic Adventure #1 and a Sonic Adventure #2.There is now a Sonic Adventure 3 - released in 2011 - the year of the Sonic 20th anniversary.
Emblems in Sonic Adventure 2 allow more content to be bought from the Black Market in Chao World, including character menu themes. Collecting all 180 will unlock a 3D version of Green Hill Zone.
There is no cheat, but Action Replay might have codes that helps you get all 180 emblems easier.
No. The last Sonic Adventure was Adventure 2 which was released in 2001. I doubt there will be another Sonic Adventure but in a interview a member at Sega he likes the idea of remaking Adventure 1.
No he cant. Only on sonic adventure, sonic adventure 2, sonic DX and sonic adventure 2 battle.
In story mode(adventure tours) complete ten missions with one character then you will have that characters emblem
Sonic Adventure happened in 360.
No, Sonic Adventure 2 is only on Dreamcast and Gamecube as Sonic Adventure 2 Battle.
There is no such thing as Sonic Adventure Battle 1, nonetheless no Sonic Adventure is playable on Sonic Mega Collection.
No there isn't a Sonic Adventure 3, there should be though the Sonic Adventures were good games. there is kinda sonic unleashed or in japan sonic world adventure is supposed to be the third instalment in the sonic adventure series
