Practical Play Notes

Control Sonic through time-traveling platforming by moving through zones in past, present, or future timelines, using signposts and speed to shift them.

• 1. Basic Platform Controls: Movement: Use arrow keys or WASD to run left and right, and press Down while standing to crouch. Jump: Press Space or Z key to spring into spins or bounce from enemies. While moving, try a rapid tapping motion to build speed.
• 2. Trigger Time Travel: Find metal POST signposts labeled PAST or FUTURE in a zone; then race around the level holding a top running speed until a time warp portal appears; jump into warp stars inside to activate travel.
• 3. Future Determination: Visit the past zone and break its metallic project generator, then complete level to lock a GOOD Future; leave the generator intact for a BAD Future ending screen.

Practical FAQ

How do I access the special stages in Sonic CD?

To access a special stage, pass a checkpoint lamppost with at least 50 rings; you'll launch into a 3D UFO chase minigame where you must run into enough spherical blue targets to claim the Time Stone.

What happens when I get all the Time Stones?

Collecting all seven Time Stones automatically triggers the best ending sequence, creating Good Futures in all zones by default without having to destroy the Metal project generators in the past.

Can I play through all past, present, and future zones in one run?

Yes, but you can't permanently alter a single zone's future once it's complete; however by replaying you can explore all possible times to fully understand the storyline impacts on each zone.
