Using elytra in the 1×1 space in the area above the barrier grants the 'supersonic' achievement. In older versions like PlayStation 3, escape is possible with an elytra or a fishing rod, but the final version has one known way put of the lobby: abusing a glitch that causes the blocks in the nether portal opening to become intangible and using an elytra to escape. The main collectables and secrets of the lobby are getting the music discs, getting all of the armor sets, the hidden old lobby, and the mob head hunts to get the the dragon's head. There are many redstone puzzles scattered around. When playing with other players, the next game starts within one minute, although the player can create an invite-only game to gain the freedom to explore the lobby. All players are in adventure mode and are immune to damage (just like in creative mode). It is a small 'town' in the middle of a superflat world. Upon creating or joining a server, the player spawns in the lobby.
