Loftia Underground Pillars: What We Know About Gridfall's Secret Tunnels

The Short Answer on Loftia Underground Pillars

The official marketing pages do not name an underground-pillar landmark, but beta data documents a real quest objective: Beneath the Surface requires repairing 3 Repairable Underground Pillars in The Gridfall.

This guide separates the official Gridfall tunnel features from the beta-data pillar objective, so you can distinguish a named quest object from general underground scenery.

What Are the Loftia Underground Pillars?

Gridfall is Loftia's salvaging district — a "concrete jungle built from scraps and love on the remains of the old world." According to Loftia's official Early Access page, the district's selling points include air rails, towering skyscrapers, a museum, and "secret underground tunnels" you can explore with friends.

That official page confirms underground space, while the beta-data quest record adds the more specific Repairable Underground Pillar objective.

The pillar term is not just descriptive architecture in beta data. During Beneath the Surface, the quest step explicitly requires repairing three underground pillar objects before returning to Mita.

Confirmed vs. Community Reports

Where Loftia's Underground Actually Begins

If you're determined to explore beneath Loftia, Gridfall is the district to focus on. It's reachable by air tram from Loftia City, and it's the only district the official material ties directly to subterranean content.

Two distinct systems sit under the same roof:

• Urbex (Urban Exploration): the official name for hopping down into underground areas to collect rare resources and find hidden nooks. This is the structured version of underground play.
• Treasure hunting: battery-charged doors lead into abandoned buildings and lower levels where a locator device marks dig spots.

Community footage from the beta suggests these aren't the same activity. The Urbex layer is about resources and discovery; the treasure layer is about artifacts and randomized rewards.

How the Dig Loop Works

One creator's beta walkthrough describes the flow like this: you enter through a battery-powered door, pull out the locator, and it paints a circle on the ground showing where to dig. Roughly three dig locations later, you're dropped somewhere random in the city — one run ended on a rooftop. That teleport-out is worth planning around; don't descend deep if you're mid-quest elsewhere.

Gear to Bring Before You Descend

Underground runs in Loftia are gated by tools more than by skill. Based on the beta footage reviewed, here's what experienced players prioritize.

Upgrade your hammer to level two first. One player needed 10 rattan, 10 copper strip scraps, and 2 rubber for the upgrade, with the recipe unlocked through a research station bundle rather than a shop. Without a level-two hammer, several routes and nodes simply won't break.

Get bounce shoes before Gridfall. In the beta, the NPC Cliff explains that propulsion boots calibrated to jump pads are required for navigating the district — the alternative being a very long stay in its depths. Crafting them took 2 aluminum bars, 10 resin, and 2 banana leather in one player's run.

Keep your battery topped off. Battery charge opens doors, powers machines, and fuels the dance floors that recharge you. A spare energy source at home — solar, biofuel, or water — keeps the loop from stalling.

Bring the locator and rail boots. The locator marks dig circles; rail boots open up vertical routes between rooftops and lower levels.

What's Actually Down There

Loot tables below Gridfall skew industrial. Beta footage shows sand, gears, and metal scrap from debris piles, plus algae if you fish in the sewer channels. Repairing pipes with a wrench yielded rusted metal, and fixing a broken fixture returned rust-resistant alloy.

The real prize, though, is artifacts. These feed the museum and other collection systems in Gridfall, which return recipes and rewards. If you are specifically chasing the underground pillars, progress Beneath the Surface until its repair step; the beta-data quest record requires three Repairable Underground Pillars.

If you want the official feature list rather than secondhand footage, the Loftia page on Steam is the most stable reference point for what the game claims to include.

Tips for Anyone Still Chasing Loftia Underground Pillars

• Search Gridfall, not Loftia City. The city has construction and scrap zones, but the documented underground content lives in the salvaging district.
• Do a level-two hammer push early. It unlocks nodes, routes, and research options across multiple districts.
• Group up. The official page frames underground tunnel exploration as a friends activity, and multiple dig doors are easier to sweep as a pair.
• Watch the water. Community footage is full of accidental swims; falling in costs time on timed routes.
• Log your routes. Underground layouts reportedly differ between zones, so screenshots save repeat exploration.
• Use the quest step as your anchor. The beta-data record ties the pillars to Beneath the Surface in The Gridfall; use the official Discord to check whether the objective changes after patches.

Timing and Access

As of October 21, 2026, Loftia's official Early Access page listed a launch date of November 3, 2026, on Steam and the Epic Games Store, with a US$29.99 base price and a 17% launch discount to US$24.89.

The same page notes Loftia is an online MMO that can be played solo, so underground exploration doesn't require a group — though some routes are clearly friendlier with one. The Steam Next Fest demo is live October 19–26, 2026, with progress carrying over into Early Access.

FAQ

Are there Loftia underground pillars I can find right now? Yes in beta data. Beneath the Surface includes a step to repair 3 Repairable Underground Pillars in The Gridfall; official marketing pages do not document that quest-level detail.

Do I need the Urbex tool to explore underground? The official Early Access page describes Urbex as underground exploration aided by a special tool for collecting rare resources. Bring it, plus a level-two hammer and bounce shoes for Gridfall navigation.

Is underground content solo-friendly? Yes. Loftia can be played alone without blocking progress, though community footage suggests underground runs are smoother with a partner for splitting dig routes.

Which Loftia quest uses the underground pillars? The beta-data main quest Beneath the Surface uses them. It asks you to repair three underground pillars after getting an Urbex key from Mita, then return to Mita in The Gridfall.
