Green Hill (Sonic Adventure 2)

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. Far too short and easy compared to most levels, but it was made for pure novelty anyway.
