Altar Emerald
From Sonic Retro
| Altar Emerald |
|---|
| Normal Final Zone, Sonic Advance 3 |
| Number of Acts: 1 |
| Sub-boss: Gemerl |
| Boss: Dr. Eggman |
Altar Emerald is found after beating Chaos Angel's boss by moving just a bit further and finding the Final Zone Ring (though, after completing the game, you will be automatically taken to Altar Emerald after beating Chaos Angel). Its similar to Death Egg Zone in Sonic 2 in that instead of another level, its two bosses back to back (with rings, this time). The bosses of this level are Gemerl and Eggman.
After beating Eggman, if Sonic was the lead character and all 7 Chaos Emeralds were collected, the true final zone will appear, Nonaggression. If not, the normal ending will play.
