Master Part 25 of Sonic the Hedgehog with our comprehensive guide. Includes walkthroughs for New City, Radical Train, Aquatic Base, boss fights, and town missions.

Walkthrough
  1. 1
    New City: Near the Shop
    • Mission: Meet up with Rouge in the warehouse district.
  2. 2
    Support Character: Omega.
  3. 3
    New Item: Memory Shard (Red) - 6000 Rings.
  4. 4
    Objective: Head to the warehouses. You can optionally buy the Red Memory Shard. Jump over the wall or gate to find Rouge.
  5. 5
    New City: In Front of the Warehouses
    • Mission: Head to the station!
  6. 6
    Objective: Go straight, then turn right at the large gray building to find the train station entrance to Radical Train.
  7. 7
    Act 5: Radical Train
    • Act Type: Race, Vehicle.
  8. 8
    Vehicle: Motorcycle (necessary).
  9. 9
    Mission: Follow Dr. Eggman!
  10. 10
    Difficulty: Medium-Hard.
  11. 11
    Enemy Type: Eggman Robots.
  12. 12
    Objective: Stop the train by finding switches to allow attacks. Ignore enemies and reach switches quickly.
  13. 13
    Switch Locations: Both switches are near a closed door.
    • Switch 1: Under the two boxes to the right of the door.
  14. 14
    Switch 2: In a cage; defeat three enemies to open it.
  15. 15
    Traversal Tips: Jump across scales quickly. Run on the ledge between conveyor belts if needed.
  16. 16
    Motorcycle Tips: Steer carefully, use boost ramps with precise timing to avoid smashing into trains. Fire the machine gun at the train to destroy it; proximity isn't critical. If the motorcycle is heavily damaged, Shadow may not be able to catch up if he falls behind. An alternative motorcycle exists at the start, but skipping the first may make catching up harder.
  17. 17
    Hard Mode Tip: Both switches are heavily guarded by enemies.
  18. 18
    S-rank Tip: Prioritize enemies worth many points for Hard Mode to meet the time limit; don't kill everything. Keep Rings.
  19. 19
    Boss 4: Silver the Hedgehog
    • Mission: Defeat Silver!
  20. 20
    Difficulty: Medium-hard.
  21. 21
    Strategy: Silver uses psychokinesis to throw you. He must be close to use powers. Run away when he targets objects, then attack. He yells "How about this!" or "Take this!" when using powers. Use a running kick instead of a Homing Attack to avoid being thrown. Chaos Spear can make him fall but not stun him.
  22. 22
    S-rank Tip: Stay in the center, moving back and forth. Frequently check if he has stopped and picked up objects. Use Chaos Spear to knock him down and escape if he gets too close.
  23. 23
    Act 6: Aquatic Base
    • Act Type: Support Character, Vehicle.
  24. 24
    Support Character: Silver (meet), Shadow follows Silver.
  25. 25
    Vehicle: Motorcycle (optional).
  26. 26
    Mission: Follow Mephelis!
  27. 27
    Difficulty: Medium.
  28. 28
    Enemy Type: Monsters.
  29. 29
    Tips: Hitting lava worms with the motorcycle counts as multiple hits. Use Homing Attack on silver balls to cross gaps; Chaos Boost may interfere. Activate cylinder-shaped devices by attacking them to turn them blue, killing nearby enemies and drawing small bubbles for points.
  30. 30
    S-rank Tip: In Normal Mode, clear all enemies. In the last battle room, don't collect Ring Item Boxes before fighting enemies to avoid losing Rings if hit. Hard Mode has enough enemies for an S-rank.
  31. 31
    Castle Town: In Front of the Gate to New City
    • Mission: Get the Scepter of Darkness!
  32. 32
    Support Character: Rouge.

  35. 35
