Egg Hangar is a race track in Sonic & Sega All-Stars Racing, and is a DLC track set within the Death Egg Zone as it was originally represented in the Death Egg Saga of the original Mega Drive Sonic games. This particular course isn't in the game at first, but can be added via DLC, along with Metal Sonic as a playable character in the game.
This track also appears in Sonic & All-Stars Racing Transformed as the final track of the Classic Cup with a few modifications.
This track goes both inside and out of the station, with numerous sweeping turns and even a split with two routes (upper and lower). The Final Weapon makes an appearance here flying around the ship, and even Ristar makes a cameo here in single player mode, waving at the player. The Ristar cameo was removed in Transformed, due to him becoming the game's flagman.
Note: In Transformed, only Cosmic Fall will play.
