Knuckles' Chaotix (1995)

Knuckles' Chaotix is a side-scrolling platform game developed and published by Sega for the 32X. Gameplay is similar to previous Sonic games: players complete levels while collecting rings and defeating enemies. Knuckles' Chaotix introduces a partner system whereby the player is connected to another character via a tether; the tether behaves like a rubber band and must be used to maneuver the characters.
