"A Sonic 3 A.I.R. mod that adds Knuckles as a 3rd AI companion when playing as Sonic & Tails. Knuckles isn't buying Eggman's lies this time — he joins the team from the start.
Features
3-Character Gameplay — Sonic, Tails, and Knuckles all on screen at once
Character Swapping — Press Y to cycle control between all three characters
3-Person Formations — Tails can carry a chain of all three characters; Knuckles can glide-carry Sonic
Hyper Form for All — When one character transforms, all three go Hyper with rainbow palettes and Super Flickies
Both Paths Unlocked — Sonic's and Knuckles' paths are accessible in every zone, with player-activated buttons replacing NPC Knuckles cutscenes
Blue Spheres Support — Knuckles appears as a 3rd character in special stages
Custom AIZ Intro — New opening cutscene where Knuckles sees through Eggman's deception"
