Fusion Engines

The **Fusion Engines** is the fourth area of Chapter 1, and starts right after stepping into the activated Master Teleportal. In this section, your objective is to shut down the Fusion Engines.

## Walkthrough

The Master Teleportal will warp you into some cabling tunnels. It is possible to use your Laser Drill to cut through the cables as you navigate them.

Eventually you will fall down into a medium-sized hallway containing some drones, including some Phaser Turrets, the first Repair Drone you will encounter, and a Heavy Worker Drone. Once you defeat them all, break through the glass at the end of the hallway to enter the main room of the Fusion Engines.

In a cutscene, Hyso will explain how to destroy the Fusion Engines. At first it basically boils down to using a hacked drone to hack all four Drone Identification Slots. The structure of the Fusion Engine area has two levels, and two sides - the deuterium (pink) side and tritium (green) side. Two Drone Identification Slots are located on each side, and on each side one is on the first level and the other is on the upper level, accessible by some stairs that can be reached from the back area near a Matter Manipulator.

Once you hack all four Drone Identification Slots you can access the second level of the central area from either the second-level Deuterium or Tritium room. In the centre at the front of the engine, you can hack one more Drone Identification Slot to disable the magnetic field.

While this disables the Fusion Engines, more drones begin spawning in from the spawners in the Deuterium and Tritium rooms (even if they were turned off). Hyso voices concern that they could just simply turn the engine back on, and says you need a more permanent solution.

The instructions he outlines are to craft and place 16 Fusion Charges on the teal-highlighted blocks around the outer edges of the main Fusion Engine room, as well as a Fusion Detonator, an Oxygen Mask, and to upgrade your Metal Boots to Magnetic Boots.

The first thing you’ll need to accomplish this is glass shards, at least a stack of them. You can get them from breaking the glass in the Deuterium and Tritium rooms. Next, craft them into Empty Cells, and place them into the Deuterium and Tritium dispensers on the second level of the main Fusion Engine room, which will fill the cells with Deuterium and Tritium respectively. 32 of each will be enough for 16 Fusion Charges.

As for the rest of the items, most should be readily craftable fairly easily. The Oxygen Mask needs two Oxygen Cells, which can be obtained by filling Empty Cells with oxygen in the Oxygen room, which is located behind the Fusion Engine on the second level.

Once you have crafted everything and placed all the Fusion Charges, Hyso will direct you to the Oxygen room (a glowing green highlight will appear at its location). There he will tell you to use the Fusion Detonator, which you can do by right-clicking with it. This will detonate all of the Fusion Charges, resulting in a massive explosion, and you black out.

When you come to, you find that the entire area has been decimated, fragments of all the rooms and tubes only just holding together. You are also now exposed to the vacuum of space, an indicator saying your oxygen level is at 70% being displayed.

Before you can leave the room, you have to use at least one Oxygen Cell to top up your oxygen. There is a free Empty Cell in a box in the room, which you can fill with oxygen if you don’t have any left over.

Afterwards, you can leave through the hole in the wall. There is a drone spawner that can be turned on to get more glass shards for more Oxygen Cells, though you probably won’t actually need to use it. Hyso will instruct you on how to get out of the area, which involves climbing through and across several tritium and deuterium tubes. Once you get back to the hallway area that you initially entered the Fusion Engines through, Hyso will say that he is being cut off, and his voice disappears in static. In the cutscene you then walk forward and into a room that wasn’t previously accessible, where you step onto a small teleporter that takes you to the next area.

## Equipment

 Freeze Ray - 6-11 Ranged Damage. Shots inflict Slowness for 3 seconds, at a high enough potency that it stops most mobs from moving. Crafted using 3 Metal, 1 Metal Grip, 1 Laser Cell, 2 Laser Barrels.

 Static Emitter - Right-click while holding to emit an AOE static burst. Deals 4-6 damage to all enemies within 6 blocks, and it also inflicts Slowness and Disintegration (wither) for 10 seconds. Crafted using 8 Electric Cells, 1 Electro-Magnet.

 Fusion Charge - 1 Fusion Cell, 1 Drone Part and 1 Wireless Receiver in that order top to bottom. You get 2 per craft.

 Fusion Detonator - 1 Wireless Transmitter, 4 Electric Cells, 4 Metal. Right click to use it. However, it won’t do anything until Hyso tells you you can blow the Fusion Charges sky-high.

 Oxygen Mask - No Armor. Allows you to breathe in space and other areas with no oxygen for a limited time. Your oxygen will drain at a rate of 1% every 1.5 seconds, meaning you can survive 150 seconds (2 and a half minutes) before running out. When you craft it, it is unique item in that it cannot be equipped manually; instead when one player crafts it, everyone will automatically get it equipped. The recipe will be cleared so you can’t craft it again.

 Magnetic Boots - 1 Armor, Allows you to stick to the ground in zero-gravity conditions. Similar to the Oxygen Mask when one player crafts it everyone will automatically get it equipped, and the recipe gets cleared. Crafted using: 1 Metal Boots, 2 Electro-Magnets.

## Recommendations

The Freeze Ray and Static Emitter are not required, though they can be useful. The Freeze Ray can be loaded outside of battle and fired instantly to stun an enemy while in battle, while the Static Emitter can deal damage to a large group of enemies and also slow them.

It takes the following amount of resources to craft everything required in this section:

- 16 Fusion Charges: 32 Deuterium Cells, 32 Tritium Cells (overall needing at least 64 Glass Shards), 48 Drone Parts, 4 Electric Cells

- Fusion Detonator: 32 Drone Parts, 5 Electric Cells

- Oxygen Mask: 20 Drone Parts, 7 Glass Shards, 2 Oxygen Cells (which need at least 2 Glass Shards)

- Magnetic Boots: Your existing Metal Boots, 12 Drone Parts, 3 Electric Cells

Total: 32 Deuterium Cells, 32 Tritium Cells, 2 Oxygen Cells (which need 66 Glass Shards total), 12 Electric Cells, 112 Drone Parts

It is recommended that you collect more Glass Shards than you need and fill them all up with oxygen, as they will be useful after destroying the Fusion Engine, and for staying outside longer at the beginning of Chapter 2.

You can also try crafting more Fusion Charges than needed as well, as after completing this area you can place them anywhere and use them in combat, however mobs (such as the Exploder Drone) do begin dropping most of the items needed to craft them more often.
