Begin the lock-on adventure
Choose a saved character file and learn a controlled rhythm before chasing speed.
Original 1994 Mega Drive/Genesis lock-on game, made by connecting Sonic the Hedgehog 3 to Sonic & Knuckles. Routes and transformations refer to that cartridge combination. Sonic Origins changes and fan-made editions are outside this guide. The cover image shows original Sonic 3 component packaging.
Choose a saved adventure
Use Data Select and choose Sonic, Tails, Knuckles or Sonic and Tails on an unused save file. A saved adventure is a useful foundation for a long Emerald hunt. For a first session, choose the hero whose movement you want to learn and stick with that file. The opening of Angel Island gives room to practice without requiring you to understand every hidden path immediately.
Roll, jump and brake deliberately
The three main Mega Drive face buttons jump. Hold Down and tap jump to charge a Spin Dash, then release Down to launch. Practice a short dash on safe ground before using it beside a pit. When exploring a new section, slow down near ledges and unfamiliar machines; a rolling character is hard to steer precisely when the ground changes unexpectedly. Build speed where you can already see the route.
Keep a ring and touch the checkpoint
An ordinary damaging hit scatters your rings instead of costing a life when you have a ring to lose. Recover a nearby ring promptly, then retreat from the hazard that hit you. Touch star posts as you pass them so a lost life does not erase the whole act's travel. Rings and shields are help for combat, but do not make a bottomless pit or a crushing platform harmless.
Finish the act before hunting every detour
On an unfamiliar act, identify its basic route and boss first. You can return to exploration with a better understanding of the terrain. Pause on a stable platform to decide whether a suspicious wall or lower passage is worth testing. If you repeatedly lose lives while searching, concentrate on reaching the next checkpoint before trying another risky experiment. An Emerald collection is easier to pursue when the ordinary stage is familiar.
Use a short Spin Dash for a controlled launch; maximum speed is useful only when you know where it leads.
