Full Game Structure: Three Routes and the Last Episode
The Sonic the Hedgehog 2006 full game experience is organized around three parallel story campaigns that converge into a shared finale. Sonic's route follows his rescue of Princess Elise, Shadow investigates Mephiles and the future catastrophe, and Silver hunts the "Iblis Trigger" across a ruined timeline. Each campaign mixes action stages, boss encounters, and Soleanna town sections, and the Last Episode only unlocks after all three are finished.

| Campaign | Focus | Signature Stage | Final Boss |
|---|---|---|---|
| Sonic | Speed platforming, rescuing Elise | Wave Ocean | Egg Wyvern |
| Shadow | Combat, Chaos powers, vehicles | White Jungle | Mephiles |
| Silver | Psychokinesis puzzles, future ruins | Crisis City | Iblis |
| Last Episode | Finale with all three leads | End of the World | Solaris |
New players should start with Sonic's campaign. It teaches the core movement systems that Shadow and Silver stages later assume you already understand.

Boss Strategies for the Full Run
Boss fights in the full game reward patience over constant aggression. Every major boss exposes a vulnerability window only after finishing its attack animation.
Egg Cerberus
- Circles the arena after each charge
- Attack only the exposed target post-charge
- Avoid standing center-stage
Mephiles
- Creates copies with dark projectiles
- Track the attack source, not the clones
- Use Chaos abilities to create openings
Iblis (Both Phases)
- Throw debris with Psychokinesis
- Watch ground markers before fire impacts
- Save objects for the next vulnerability window
The final Solaris battle in the Last Episode is divided into character sections: Shadow handles Mephiles, Silver fights Iblis, and Super Sonic finishes Solaris across multiple phases.
| Boss | Campaign | Weakness Window | Key Risk |
|---|---|---|---|
| Silver (rival fight) | Sonic | After he releases lifted objects | Standing in front of telekinetic throws |
| Egg Genesis | Shadow | After sweeping attack sequences | Chaos Control without escape room |
| Egg Wyvern | Sonic | During aerial pursuit | Missing ring trails, falling low |
| Solaris | Last Episode | Designated Super Sonic openings | Entering with too few rings |
Collect a strong ring supply before the Super Sonic section. If rings drain before the next vulnerable phase, the transformation ends and the attempt fails.
Step-by-Step: Reaching the True Ending
Complete Sonic's Episode
Finish all of Sonic's stages, defeat Egg Cerberus, Silver, and Egg Wyvern, and complete the episode ending sequence.
Complete Shadow's Episode
Clear Shadow's combat and vehicle stages, defeat Egg Genesis and Mephiles, and finish the campaign ending.
Complete Silver's Episode
Master Psychokinesis platforming, defeat both Iblis phases, and conclude Silver's story.
Unlock the Last Episode
Return to the main story menu and select the newly unlocked Last Episode after all three campaigns are complete.
Defeat Solaris
Use Shadow against Mephiles, Silver against Iblis, then Super Sonic to finish all Solaris phases and watch the true ending.
Town missions are optional for story completion but provide extra rewards, practice, and progress toward Gold Medal and 100% completion goals.
100% Completion Checklist
Full Game Completion Goals:
- Complete Sonic, Shadow, and Silver episodes
- Unlock and finish the Last Episode
- Collect Silver Medals in every action stage
- Complete Soleanna town missions
- Earn S Ranks on stages and missions
- Collect Gold Medals across Soleanna
- Finish platform achievements on Xbox 360 or in-game goals on PS3
| Collectible | Location | Best Method |
|---|---|---|
| Silver Medals | Action stages | Dedicated exploration runs, check side paths |
| Gold Medals | Soleanna town areas | Flight, climb, glide, dig, Psychokinesis |
| S Ranks | Stages and missions | Rehearse routes, minimize damage, keep rings |

Do not combine medal hunting with S Rank attempts. A clean exploration run is more reliable than splitting focus between speed and searching.
FAQ
Q: How long is the Sonic the Hedgehog 2006 full game?
A story-focused run covering all three campaigns and the Last Episode typically takes most players several evenings of play. Full completion with all medals, S Ranks, and town missions takes considerably longer.
Q: How do I unlock the Last Episode in Sonic the Hedgehog 2006?
Complete the final story sequences for Sonic, Shadow, and Silver. The Last Episode then appears on the main story selection screen and leads to the Solaris final battle.
Q: Can I play the full game on PC?
The game originally released on Xbox 360 and PlayStation 3. The unofficial Marathon Recompiled project offers a native PC option using the Xbox 360 version, but it requires legally obtained original game files.
Q: Are town missions required to beat the game?
No. Town missions are optional for basic story completion, but they contribute rewards and are needed for 100% completion, Gold Medal progress, and rank improvement.
