How to unlock the Shadow Episode: Completed achievement in SONIC THE HEDGEHOG - Definitive Guide

Just complete every ACT mission on HARD mode. Unlocked after beating the game normally and accessed by looking under the mission select tab.

You don't have to replay bosses. Hard mode just changes up the enemies, adds more traps, moves switches around and sometimes takes away springs.
