This 100% totally needed guide will tell you how to get the Anniversary achievement with very little work.
Setting up your game
Open CastleMinerZ by going to Steam>Library>CastleMinerZ>Start.
Then, click anywhere to go to the title screen.
Next, host a game. On the “Choose a Game Mode” screen, select Endurance. Endurance mode is required to get any achievement for this game.
When the loading bar fills, the game will load the map. Yay.
If you hosted your game online, you will need to go private. This is to stop people from joining your game and getting you killed. Pause the game, then Options>Host Settings>Invited Friends.
Creating your Complex Survival Base
Make sure to find a place far away from cave systems. Enemies can break blocks and if there is only one block protecting you from danger then you’ll totally die.
Using what you have learned, dig straight down, ignoring any consequences coming with this.
Point your cursor at the farthest block away that you can reach. Next, place blocks until your can no longer do such. This complex building method, only mastered by professional miners, will protect you from all harm.
Mine a single block above you, then place a torch directly above you. OOOoooo000ooooooOOOO AAAaaaaHHHHhhhhh pretty stik
Preparing for Long Term Survival
This is the hardest part of the guide, as you must free your mouse from the game. You must Alt+Tab into another window, then move your mouse over the CastleMinerZ minimize button, then click it. No, there’s definitely not an easier way to do this.
Do literally anything else until the achievement unlocks. Just don’t turn off your PC or anything, the game has to stay running.
