Lobby

The Bell: Ring the Theater Bell
You unlock this by completing the hidden lobby parkour. Climb the copper fire escape on the green building, outside and to the left of the Cinema. From here, you can parkour across the building facades to get to the Cinema Roof. Climb the lights to reach the bell at the very top and ring it.


Vineyard

Lance: Find Lance the Turtle in Vineyard
In Vineyard, enter the sewers through the fountain. From here, follow the west corridor to the very end. Turn right to find Lance.

Away from prying eyes: Unlock the Vineyard's main attraction
Gather plants from flower pots - you'll find most of these on the top floor greenhouse of the mansion. Use these plants to fill the composter in the shed in the northwest corner of the map and obtain bonemeal. You can then use this bonemeal on any cocoa pod (there's one near the shed, and many others in the vineyards) to obtain the "Grapes" item. You can use these grapes to open the brewing stand located in the distillery (the building next to the shed) and obtain "Wine". Drinking this wine will invalidate the achievement. Instead, go down the Distillery's sewer entrance. At the bottom of the stairs look up and you'll see another brewing stand in the ceiling. Placing the unused Wine in this brewing stand will open a new tunnel immediately to your south. Follow this tunnel into the speakeasy where you'll see a jukebox. Press the button on the jukebox to earn this achievement.


Library

Thriller: Awaken the Blood Moon in Library
For each Library match, 5 books will spawn on the side of bookshelves throughout the map. There are 18 possible locations for these to spawn; 5 spots on the bottom floor, 3 on the second floor, 7 on the third floor, and 3 on the fourth floor. Once found, right click a book to pick it up, then drop books in the Book Return on the west side of the first floor. Returning 2 books will open the basement entrances, while returning 5 books will begin the Blood Moon event. To complete the event, head to the westernmost wall in the basement, open the book on the lectern in the room below, and click "Proceed".


Floating Islands

Airship Captain: Enter the Captain's Quarters
Flick the lever inside the airship at the coordinates -632 52 -6. Obtain a teleportation crystal (you can get one by punching an amethyst crystal with particles around it, found around the western islands) and stand in front of the captain's quarters door at -636 56 3. Right click while holding the crystal and facing the door to teleport inside and earn the achievement.


Launch Complex

Rocket Rider: Ride the Rocket in Launch Complex
First, players must find and press 10 stone buttons hidden throughout the map. The button locations are:
1. Inside the car on the launch pad
2. In the pool of water directly underneath the rocket
3. On the bottom of the liquid hydrogen tank in the southwest region of the map
4. On the top of the liquid oxygen tank in the southeast region of the map (use the stairs to get up)
5. Underneath the yellow crane (look up while directly below it)
6. On the back side of the andesite cylinder in the hangar nearest the rocket
7. On the side of a dispenser on the middle shelf in the northwest corner of the hangar
8. Underneath the blackstone shelves in the garage of the Launch Control Center (the entrance is on the north side of the building, on ground level)
9. On one of the desks in the mission control room on the second floor of the Launch Control Center (one of the iron pressure plates is replaced by a button)
10. On a wall in the underhang connected to the east edge of the launchpad, next to the tunnel entrance
Once all buttons have been pressed, the launch countdown will begin. Before the countdown runs out, any players that want the achievement must go to the black support structure next to the rocket and use the now unlocked elevator to enter the rocket. Once on board, press the "Go for Launch" button. After it is pressed, any players inside the rocket when the countdown ends will earn the achievement.


Murder on the Mississippi

How about a game?: Play the Dead Man's Hand
There are 5 playing cards hidden throughout the map: 3 Ace of Spades, and 2 Eight of Spades. Their locations are:
Aces:
  - On the counter of the kitchen on the top deck
  - On a shelf on the western side of the middle deck, at the end of the central hallway
  - On a small green table in the game room on the lower deck
Eights:
  - On top of the drum set on the east side of the top deck
  - On top of a noteblock on the southeast side of the lower deck, near the waterwheel

Players must take all cards to the game room in the middle of the lower deck, and place them on the long green table in the following order (from left to right when facing the window): Ace (face down), Eight, Ace, Ace, Eight

If placed correctly, a sound will play and a new door to the captain's quarters will open on the top deck. Enter and right click the chain next to the helm to earn this achievement.


Color Filth

Felines and City Chimes: Discover the music in the loud cyber city
This achievement is done in multiple parts. First, players must find and right click 9 Lucky Cat statues hidden throughout the map. Their locations are:
  - White: On the east side of the inside the ship in the center of the map (go up the smooth stone steps)
  - Black: On the counter of the spruce food stand near the ship
  - Aqua: On the counter of the copper food stand behind the spruce one
  - Yellow: On the wall of the "Babel" building on the east side of the map (walk in, then turn around)
  - White (2): On a shelf in the building with birch trapdoors on the southeast side of the map
  - Blue: On a shelf in the restaurant on the southwest side of the map (on a red wall in the dining area)
  - Black (2): Behind iron bars in the southwest region of the map (near the restaurant, you may need to crouch to reach)
  - White (3): Behind iron bars in a southern alcove of the map (near Panter)
  - Aqua (2): On a jungle trapdoor shelf in the mechanic shop, just west of the central ship

Before the next part, players should meet Panter the black cat, located directly south of the central ship. Panter will meow when a player has "met" them. After all the Lucky Statues have been activated, you can use the elevator in the Babel building to enter the rooftop garden, where you'll find Pester the black cat on the southern side. Meet Pester by having them meow, then head back to the ground level.

For the last part of this achievement, you must ring the bell contained in the central ring of the gate in front of the Babel building. This is most easily done by shooting it as a gunner, but it is possible (though difficult) to do with a thrown knife as murderer. If all the steps have been done correctly, ringing the bell will grant the achievement.


Tragedy on the Boreal Express

A Nice Meal: Enjoy dinner with a fellow passenger
This secret requires 2 players. Go to the table with food at the coordinates 1842 113 3001, and have both players sit down on the chairs. Have both players sit for at least 30 seconds to earn the achievement.

Exploring Maps:
To explore maps outside of matches, you must first join the Developer Team using the command:
/function mcm:dev

Entering this command will let you bypass bounding box restrictions, letting you teleport anywhere, and also bring you to the Debug Room which has teleports to every map.

To return to normal gameplay, leave the Developer Team using the commands:
/team join nametags [​Player Name]
/gamemode adventure
/tp 1 1 70 (if you wish to return to the lobby)


Shuffle Maps:
To shuffle which maps are shown in the Voting area in the lobby, enter the command:
/function mcm:dev/shuffle_maps


Toggle Maps:
You can toggle whether a specific map can appear in the Voting area. This can be done per map using the command:
/function mcm:dev/toggle/[​map name]

For example, entering the command /function mcm:dev/toggle/airship will either disable or enable the Floating Islands map. Note some maps have internal names different from their displayed names.

You can enable or disable all maps using the respective commands:
/function mcm:dev/toggle/enable_all
/function mcm:dev/toggle/disable_all


Creating Fake Players:
You can start a game using fake players for testing purposes. To do this, use the command:
/function mcm:dev/fakeplayers

This will spawn armorstands in the lobby by the cosmetic equip area that function as fake players, allowing you to start a match with only 1 or 2 real players. Note that if only 1 real player is present, the match will end immediately.

To remove the fake player armorstands, while in the lobby enter the command:
/kill @e[​type=minecraft:armor_stand,tag=fakeplayer,tag=queued]
