One of the first tasks you will be given in Grounded is finding out what is weakening the laser at the Mysterious Machine. This quest actually entails quite a bit of crafting and is designed to introduce you to some of the game’s mechanics.
The first thing you will need to do is make sure you have access to the Woven Fiber recipe, which is very important for this quest. To get the Woven Fiber recipe, analyze some Plant Fiber in the Analyzer at the Field Station. You will also need a weapon, so make yourself a spear, as it has a good range.
Head for the tower
Now, make your way toward the tower that the weak laser is coming from. When you get there, you will notice that small red bugs are eating into the wire. Kill them, loot the smashed bug corpses, and then get ready to head down into the dark.
You will need to make a Torch first, so be sure you have one on you as it is impossible to see down in the tunnel.
Down in the dark
Now, venture down into the tunnel, kill any bugs you find, and make sure to watch the wire and kill any bugs eating into it. You will know you have reached the end because the wire will disappear into the ground, and there will be a wall with an icon on it when you stand close to it.
You don’t need to go any further, but if you have the Peblet Hammer, you can smash down the wall and get some important resources. When you are done in the tunnel, return to the Mysterious Machine, and the laser will be firing at full power.
