Newtrogic High Zone

Newtrogic High Zone
Overworld level, Knuckles' Chaotix
Number of Acts: 0
Boss: Knuckles' Chaotix penultimate boss
Prerequisite: Isolated Island

Newtrogic High Zone is the setting for most of Knuckles' Chaotix - with the exception of the first level, Isolated Island, which depicts Knuckles and Espio's approach to the area. The US and Japanese manuals tell completly different stories about the Zone's provenance, but the latter states that it's a theme-park-esque facility constructed by Dr. Robotnik in order to (somehow) expedite his search for the Chaos Rings.

Functioning as a sort of playable options screen for Knuckles' Chaotix, Newtrogic High Zone's entrance is where the player starts on loading up a save state. From here a second member of Chaotix can be plucked from the Combi Confiner, and the semi-random level selector determines which of Newtrogic High's five constituent areas are to be played next.

The apparently harmless level select machine ends up functioning as the penultimate boss battle, when Metal Sonic interfaces with a hidden docking mechanism and pits the substance of the level itself against the player!
