10 Video Game Easter Eggs STILL Undiscovered

10. The Live Sega Chant - Sonic Mania

Sonic Mania was first announced at Sega's 25th anniversary event for Sonic during San Diego Comic-Con, and during the show Sonic Team producer Takashi Iizuka even had the live crowd record a rendition of the iconic "Sega!" jingle to be included in the game as an Easter egg.

Iizuka had two takes from the crowd recorded for safety, and yet, more than six years removed from Sonic Mania's acclaimed release, the live Sega chant still hasn't been found.

While players might've expected to hear it in the game's opening screen or perhaps during the end credits, it's present in neither case.

Players have extensively trawled through Sonic Mania in an attempt to unlock the jingle and even datamined it to no avail, leaving fans wondering quite how to trigger it.

Others have speculated that the Easter egg may have been cut during development due to the sound quality being too poor, yet to date there's still no concrete word from anyone involved with the game on that.
