Green Hill (Sonic Adventure 2)
From Sonic Retro
- For other similarly named levels, see Green Hill Zone (disambiguation).
Green Hill is a bonus level in Sonic Adventure 2, which is unlocked by obtaining all 180 Emblems and A Ranks on all Missions (barring Cannon's Core in the Dreamcast Version), that is essentially a 3D version of Green Hill Zone Act 1 from Sonic the Hedgehog. This version stays very true to the original, with appearances by classic enemies, though it does twist and turn along the third axis, unlike its predecessor.
