Part 23

Silver's Episode Boss: The boss throws objects at you, and you must throw them back. Be careful, as the boss can destroy your platform if it gets too close. Use your kenesis (a special ability) on the marker that appears on the boss's head to deal damage. Throwing rocks also contributes to damaging the boss. During the flaming rock attack, stand at the edge and press the Special Action button to catch and throw back flaming rocks. These rocks will also remain on the platform. During the major meteor attack, you can catch the large meteor with kenesis and throw it back for significant damage; failing to catch it will destroy your foothold.

Shadow's Episode - Act 1: White Acropolis: This act is a Support Character and Vehicle mission. The mission name is "Rescue the captured Agent!". Rouge will assist you for one section, and you will need to use a Buggy to finish the level. The difficulty is easy-medium, with some searchlights being tricky to reach initially. Enemies are Eggman Robots.

Shadow's Episode - Act 1 Tips: You can destroy searchlights with a Homing Attack for 1000 points, but these will not count towards the S-rank at the end of Shadow's level unless shot down with the buggy. If the buggy is destroyed, another can be found nearby. Some searchlights require driving up narrow ramps, so be cautious. Searchlights can be destroyed from a long distance. Driving up the ramp with Sonic's checkpoint (an auto-save point you restart from on death) allows you to destroy all three high searchlights from that position.

Shadow's Episode - Act 1 Hard Mode Tips: Shadow's first switch is under a pile of rocks. For Rouge, find three keys: two are in rooms sealed with ice that can be broken with bombs, and the third is in the ground and requires a bomb to break a patch of ice. Shadow's searchlight section has a new area with an ice wall and a curved ramp, typically traversed by Sonic.

Shadow's Episode - Act 1 S-rank: Kill many enemies and destroy the searchlights.

Boss 1: Egg Cerberus: The mission name is "Defeat Egg Cerberus!". Rouge will follow you. The difficulty is easy, but camera control can be challenging. The boss has an extra attack where it rears up and stomps. At the end, when the boss lowers its tail, you can grind on it and hold onto its horn. Steer the boss into the stadium wall to build speed and deal damage. If you don't damage it in time, you will be thrown off. If the boss jumps, avoid its landing area due to a shockwave. Later, the boss will turn away from the wall; keep trying to make it hit. The final phase will fling you off before you can hit the wall. In the air, Homing Attack the horn and steer it into the wall again.

Egg Cerberus S-rank: Grab many Rings and smash the boss into the wall 4 times quickly.

New City: Outside the Entrance to White Acropolis: The mission name is "Head for the old castle!". Rouge follows. New items in the shop are the Air Chip for 100 Rings and the Memory Shard (blue) for 500 Rings. Both are required to continue.

Forest: Outside the Gate to New City: To reach the Forest Town Area, go straight from the start until you reach the Warehouse district, then turn left towards the gate.

Forest Town Area: The bridge is out, but a line of Rings indicates a path. Buy the Air Chip to cross the bridge using the Light Dash (press Attack near Rings). You will also need the Memory Shard (blue). Continue through the forest to a clearing. Stick to the left side of the open field to find ledges leading to a cave. Inside, find a boy and an Item Box. Get the Item Box to fill your Action Gauge, then press Right Trigger to activate Chaos Boost. When Shadow glows red, he can break through rocks. Beyond the rocks is a warp hole to Kingdom Valley.

Act 2: Kingdom Valley: This is a Vehicle and Support Character act. The mission name is "Head to the Recovery Point!". Rouge finds three keys.
