Sonic 2 Heroes is a hack of Sonic the Hedgehog 2 for the Sega Mega Drive/Genesis by flamewing that allows the player to play as Sonic, Tails, and Knuckles simultaneously, similar to Sonic Heroes.

Features

The player can rapidly cycle between playing as Sonic, Tails, and Knuckles
Powerups are shared between players.
Tails can fly, swim and can carry either Sonic or Knuckles.
Knuckles can glide and climb.
Sonic can use the insta-shield.
Physics imported from Sonic 3 & Knuckles.
Graphics imported from Sonic 3 & Knuckles, particularly when they could be used to reduce the VRAM footprint.
Projectiles bounce off of Tails' tails and from Knuckles when gliding, as well as from shields, like in Sonic 3 & Knuckles.
A new HUD frees VRAM for Knuckles.
The drown timer is disabled to keep the characters close together instead of losing them when the timer counts to 0.
Amy Rose makes a cameo appearance flying the Tornado in Sky Chase Zone, Wing Fortress Zone and during the ending sequence.

(P1): Cycle through each on-screen playable character
(P2): Cycle through remaining on-screen characters not being controlled by P1
All other controls and player abilities are consistent with their traditional standards in the Sonic series.

The normal level music does NOT continue to play after collecting extra lives.
When the Speed Shoes item is collected, the music will either completely slow down or speed up ridiculously.
When the player crosses a checkpoint with 50 rings, they cannot enter a Special Stage by jumping over the stars.
Switching to a dying character will cost the player one life.
Activating the end-of-level cutscene in Wing Fortress Zone with Tails or Knuckles in lead will screw up the sequence, causing the screen to wrap constantly.
Sound Test doesn't work.

Adding 3 Player Co-op via Multi-Tap
Adding Knuckles to Special Stages
1-, 2-, and 3-player Special Stages, always defaulting to 1-player but additional players can join in by pressing start
Options screen
Hack-branded end-of-game logo.
Save games S3&K-style, possibly removing the options screen altogether as redundant;
Tails being able to carry Sonic and Knuckles at the same time
Knuckles being able to carry Sonic and/or Tails while gliding/climbing
Sonic having faster speed and/or acceleration and being able to carry Tails and/or Knuckles while running.
