I sincerely doubt it since I think only Josh, Alex, and I played this game. Regardless, the designers decided to throw in as many easter eggs as possible, and one of them included a references to one of my favorite games: Sonic & Knuckles. More specifically, the bonus stages from Sonic the Hedgehog 3 and Sonic & Knuckles. As you can see from the video, the easter references those crazy “3D” sphere-based bonus levels. If only the team put as much time into the game’s overall design as they did with these easter eggs – then I may want to go back and actually find this bonus. Rather than that, I’ll watch this video and just remember the wonderful times Josh and I had in co-op.
