Sonic the Hedgehog Part 15 covers Act 2 and Act 3, including boss fights against Silver the Hedgehog and town missions.

Walkthrough
  1. 1
    In the stadium, build up the boss's speed by hitting it so it damages the wall. If you don't damage it in time, you will be thrown off.
  2. 2
    If the boss jumps, avoid its landing spot due to a small shock wave.
  3. 3
    Keep trying to make the boss smash into the wall; it will eventually do so.
  4. 4
    Act 2: Dusty Desert
  5. 5
    Mission Name: Escape Dr. Eggman's Minions!
  6. 6
    Keep the Action Gauge charged and use the aura to cross sand.
  7. 7
    Platforms that move in and out of walls have a small ledge you can stand on next to the wall even if the platform retracts.
  8. 8
    S-rank Tip: Go off the main path to side paths with Rainbow Hoops and more robots. Jump for one Rainbow Hoop at the end.
  9. 9
    Boss 2: Silver the Hedgehog
  10. 10
    Mission Name: Defeat Silver!
  11. 11
    Silver uses psychokinesis to pick you up and throw you. He must be close to use his powers.
  12. 12
    Run away from him, and when he uses his powers on objects, attack him. He may yell "How about this!" or "Take this!".
  13. 13
    Do not Homing Attack him; use a kick or slide. Jumping near him allows him to fling you into the air, causing you to lose Rings and be caught again before hitting the ground.
  14. 14
    Defeating Silver unlocks his story.
  15. 15
    S-rank Tips: Hit Silver each time he stops to throw objects and grab many Rings.
  16. 16
    Gem Cheats: Red and Yellow Gems are useful. Slowing Silver down with a gem allows you to run away better and gives more time to attack.
  17. 17
    Castle Town: Near the Entrance to Dusty Desert
  18. 18
    Mission Name: Go after Elise!
  19. 19
    Go straight across the bridge, between the fountain and the gate to the New City. Pass the Lieutenant with a blue exclamation point to continue to the New City Town Stage.
  20. 20
    Town Mission #5
  21. 21
    Mission Name: Who is the Captain?
  22. 22
    Location: Required Mission in Story Mode, talk to the Lieutenant in front of the gate to New City.
  23. 23
    There are five lieutenants; one is the Captain, and two are lying.
  24. 24
    Answer: Pietro, the man you talked to initially.
  25. 25
    S-rank: Go into the mission and talk to the same guy two more times.
  26. 26
    Castle Town: Outside the Gate to New City
  27. 27
    New City
  28. 28

    Go through the gate that opened after completing the Town Mission.

    Follow the largest road to find the warehouse.
  31. 31
    Jump over the guards at the gate or the wall to enter a Town Mission.
  32. 32
    Town Mission #11
  33. 33
    Mission Name: Battle at the Warehouse!
  34. 34
    Destroy all enemies in the area within 4 minutes. Look at the map (minimap (the small circular map in the bottom-left corner of your screen)) for red dots to find enemy groups.
  35. 35
    S-rank: Destroy everything in under 1 minute 30 seconds. Smash fire boxes. Red and Yellow Gems help. You can see enemy groups on your radar (radar).
  36. 36
    New City: Warehouse District
  37. 37
    Mission Name: Head for the White Acropolis!
  38. 38
    Jump over the gate, head to the path slightly to the right, and go straight until you must take a slight right again. The cave with lasers leading to White Acropolis is across town from where you started.
  39. 39
    Town Mission #12
  40. 40
    Mission Name: Open the Cave Gate!
  41. 41
    Kill all enemies so the lasers in front of the cave go down.
  42. 42
    S-rank: Destroy enemies in about 30 seconds. Rings help.
  43. 43
    Head into the cave to find the Mirror to White Acropolis.
  44. 44
    Act 3: White Acropolis
  45. 45
    Act type: Boarding, Support Character.
  46. 46
    Meet Tails halfway through; Sonic follows Tails.
  47. 47
    Mission Name: Head for Dr. Eggman's Base!
  48. 48
    Boarding steering is tricky. You don't die when hitting a wall but take damage from enemies.
  49. 49
    For the last ramp, press and hold the Jump button near the ramp, then release to perform a long jump.
Tips
  • The two large statues in the arena, if hit, do twice the damage to the boss.
  • Crash the boss into the two large statues for a good amount of Rings.
  • The Red and Yellow Gems are helpful. You can use the Yellow Gem with any other gem by turning on the shield then switching.
  • If you use the Red Gem, you can Homing Attack the boss's tail at the very beginning.
  • The platforms that move in and out of walls have a small ledge you can still stand on next to the wall even if the platform goes away.
  • You need to go off the main path and take side paths that lead to Rainbow Hoops and more robots. You need to remember to jump for one Rainbow Hoop at the end.
  • Silver has to be close to you to use his powers. Run away from him and when he uses his powers on objects you have a chance to go in for a hit.
  • Don't Homing Attack Silver; use a kick or slide.
  • If you slow down Silver with a gem, you can run away from him better and it will give you more time to attack him.
  • Go into the mission and just talk to the same guy two more times for S-rank in Town Mission #5.
  • Look to see where red dots are on the map (minimap) to find the next group of enemies.
  • Try destroying everything in less than 1 minute 30 seconds for S-rank in Battle at the Warehouse. Smash the fire boxes when you can.
  • When you get one group of enemies, the other will not always appear in front of you, but you can see them on your radar (radar).
  • Pure enemy smashing in about less than 30 seconds for S-rank in Open the Cave Gate!
  • Boarding is touchy steering, but at least you don't die when you hit a wall, but you will be hurt if you hit an enemy.
  • The last ramp you have to trick by pressing the Jump button on or near the ramp, holding it a bit, then releasing Jump, this is how to do a long jump off any ramp.
