Sonic Adventure DX Walkthrough Part 9: Last of Sonic's story

Yep, only nine parts to wipe his story off the map, ha ha! There will be another part coming up with the ending movie and credits, but it's a no-gameplay video... which is why I call this part the end of Sonic's story, lol!

0:00 Mystery Area
3:00 Stage 10: Final Egg
9:30 Boss Battle: Egg Viper

Enjoy!
