Endfield Base Facilities and Power Grid Explained

Facility searches in Endfield land on a single item page with one line of text on it. You type "fluid gas transmuting unit" or "conduit manifold," the site shows you a description, and you still do not know what the thing connects to. This page is the other half: what each facility does, what it needs, and how the pieces are meant to fit together. Everything below is read out of our own item database, which holds 93 facility entries, 10 logistics units, 4 mining spots, 3 gas vents and 7 fluid reservoirs, plus the description text of the 49 Factory stages that teach each facility in turn.

What the facility data covers

Our item database splits facilities across four type labels, and the label tells you where a facility shows up in the Facility List rather than what it does. Combat facilities sit inside the Miscellaneous group, which is why they are easy to miss when you filter for facilities.

One detail worth knowing before you build: most facilities are unlocked as templates rather than researched directly. The template is what lets the PAC construct the facility (the separate list of production blueprints is covered in the AIC blueprints and recipes guide). A handful of templates do a different job. Some unlock an extra mode or feature instead of a new building, like Pipeline Flow Adjuster, which adds the Adjust Flow option to Pipe Control Ports. Others raise a placement limit: Forges of the Sky are capped in Wuling until you work through Forge Expansion I to IV, which add one, two, four and four more placements respectively.

How the power grid works

Power in Endfield is a supply radius problem, not a cable-routing problem. Only a few facilities have to touch the grid directly; everything else gets power from a pylon, relay or nexus that is inside range. The Xiranite versions of the pylon and the relay behave differently depending on whether they sit inside the Core AIC Area, and that is the part most people get wrong.

The practical reading: keep a Xiranite Pylon or Relay inside the Core AIC Area and it finds the PAC on its own, no matter how far away you dropped it. Move the same facility outside that zone and you are back to measuring 80 meters. Two upgrades change the shape of a grid once you have them. Pylon Relaying unlocks power transmission for Electric Pylons, Relay Redistribution unlocks area power supply for Relay Towers, and with both in place a relay chain can both transmit and feed the facilities beside it. The Core AIC Area itself is not fixed either: Expansion I and Expansion II enlarge it, which pushes the free PAC connection further out.

If a production line refuses to start with everything else looking correct, the grid is the first thing to re-check. The Factory stage Thermal Bank is the game's own version of that lesson: grid output has to be raised before the AIC facilities come back online.

Facilities that run with no grid connection

Three extraction facilities work off the grid entirely, which matters when you are pushing a line into the wilderness far from the PAC. The trade is that each one wants a specific input instead of power.

These are also the facilities the Factory stages lean on when they want you to work away from the core. Hydro Mining Rig states plainly that hydro rigs use water to mine and do not need a grid connection, and Gas Extractor says the extractor does not require power to work. The Acid Resistant Pump Mk II is the odd one out among the pumps: it exists because an ordinary pump cannot move corrosive liquids.

Where the raw materials actually are

Resource nodes are their own record type, and there are only fourteen of them in the database: four mining spots, three gas vents and seven fluid reservoirs. Each one names the rig that works it.

The mining spots are a good reminder that our identifiers and the in-game names are not always the same string. The Amethyst Mining Spot carries the internal id item_minepoint_quartz_sand, Ferrium sits on item_minepoint_iron_ore, and Cuprium on item_minepoint_copper_ore. If you are matching our pages against a datamine export, that is why the names do not line up.

Gases, fluids and the transmuting units

Both transmuting units are gated behind an activation input rather than power, which is why one can sit idle on a fully powered grid. The fluid unit wants a steady supply of Liquid Xiranite. The solid unit wants Xiragen. Get the activator flowing and the unit converts in either direction.

The Gas Dispersing Unit only alters the environment while it is active, which is what makes it useful for the one production chain that cares about the air around it. The stage Streamlined Xiranite Production requires a Forge of the Sky switched to Gas and Fluid Mode to be influenced by its gaseous environment, with a Stable environment needed to finish the line. A dispersing unit plus an upstream gas supply is how you get there.

Pipes, belts and underground conduits

There are ten logistics units, five for solid goods on belts and five for fluids and gases in pipes, and the two sets mirror each other exactly. Splitters and convergers are capped at three connections in both.

Underground conduits solve the case where a surface pipeline cannot get where it needs to go. A Conduit Inlet pairs with a Conduit Outlet, and the two larger Manifold versions pair with each other; the game's own wording is that conduits transport fluids without being affected by ground surface obstruction. The stage Conduit spells out the intended use: bring Clean Water in to start producing Cuprium without cutting a surface path across the map. Once a pipe network gets dense, the control ports matter more than raw throughput, and Flow Rate Adjustment is the stage that introduces the upgrade.

One flow-management fact that is easy to miss: Fluid Pumps are limited in number, so the game expects you to use Pipe Splitters to feed Clean Water to several facilities from one pump rather than building a pump per plot. The stage Planting Unit and Pipe Splitters makes exactly that point.

Depot logistics and belt-free transfer

The Depot Bus is the part of a base that people build last and understand least. It is not a belt and it is not a storage container; it is a bus that loaders and unloaders attach to, and it begins at a port you can place anywhere in the Core AIC Area.

• Depot Bus Port is the origin of the bus and can be placed anywhere in the Core AIC Area. Sections have to chain back to it or to another active section.
• Depot Bus Section extends the bus. Once a section is active, Depot Loaders and Depot Unloaders can attach to it.
• Depot Loader moves goods from the AIC Factory into a local depot, and must sit right next to the Depot Bus.
• Depot Unloader moves goods the other way, from a local depot into the factory, and carries the same placement rule.
• Protocol Stash is the shortcut: with grid power it teleports its contents to the Depot, which is why it normally sits at the end of a production line instead of you carrying the output back by hand.
• Easy Stash is the small version, for quick access to items already in the Depot.

Two one-off unlock items sit on top of the bus: Depot Bus I sets a bus down at the Core AIC Area of the Valley IV PAC, and Depot Bus II extends it to maximum length. The stage Belt-free Transfer shows why any of this matters: complete the grid, then let the Protocol Stash move ore to the depot without a belt run.

Base combat facilities and their stats

All 18 combat facilities are Miscellaneous type items, and unlike most facility entries they carry their combat numbers in the description text. Sort the list by attack and the spread is wide: a Gun Tower starts at 609 and a Hyper Beam Tower ends at 45,375. Four of them have no attack value at all, because they are built for control rather than damage: the Medical Tower heals operators nearby, and the LN Tower, Omnidirectional Sonic Tower and Deluge Tower slow, stun and push enemies respectively.

Two things in that table are worth planning around. Sentry Tower and Hyper Beam Tower both prioritise high-threat targets on their own, so they are worth placing where the biggest enemy in a wave will walk. Surge Tower and Electrocharger Model A-2 only chain to two extra targets, which caps their value against wide waves compared with the grenade and mortar line.

A Factory stage teaches every one of these facilities

The 49 stages in the Factory category are not combat content. Each is a short construction task whose description states the rule for the facility it introduces, which makes them the closest thing to official documentation the game has. The table below covers the power, extraction, fluid, logistics and transmutation stages; the full list, including the processing lines, is on the stages page filtered to Factory.

What our data does not include

Facility descriptions are the strongest part of our database and they still leave gaps, so here is what this page cannot tell you. We have no build costs, no power draw figure for any individual facility, and no grid capacity numbers; the descriptions only say whether something requires power or needs adequate power. There is no facility level or upgrade table either, so the ranges above are the base values as written rather than upgraded ones. And while the Factory stages explain each facility, their records carry no enemy lineups or drop tables, so if you are after combat rewards the material data lives in the enemy drops guide instead.

Everything else on this page is a direct read of our item database, which you can browse by type from the item index. Gear and the sets built from it are handled separately in the gear sets guide.
