| Fifth Two-player Zone, Sonic the Hedgehog 3 |
Possibly the most popular two-player stage of Sonic 3, Endless Mine Zone is a mine zone with some characteristics from Sonic the Hedgehog 2's Mystic Cave Zone and Hidden Palace Zone, and Lava Reef Zone. One of the important features was the necessity of rock breaking in one area to win the race. The tracks also appear to overlap.
Glitch
Using debug mode, it is possible to fight a very glitched version of the Marble Garden Zone boss in this stage[1]. It is done by using debug mode, playing the gumball bonus stage, turning into Super Sonic, losing a life, then exiting with 
+ 
, going to Special Stage 2 on the level select, and (please continue). If you manage to beat the boss, the game hangs up and the Angel Island BGM starts to play. This glitch is very similar to this one.
