Megabuilding H3

Key takeaways

• H3 is in The Glen, Heywood, not Santo Domingo or Watson.
• It has a dedicated Megabuilding H3 fast-travel point outside the building.
• The standard base-game entrance is closed off, with barriers and police/security presence around the access area.
• There is no confirmed normal interior district comparable to H10’s apartment and service floors.
• Hacking the Hacker does not occur in H3 It uses Megabuilding H6 in Arroyo.
• Videos showing H3 interiors generally demonstrate glitches, exploits, free-camera movement or other unintended access rather than a normal playable route.

About this guide

Overview

Megabuilding H3 is a large residential megastructure in The Glen, a subdistrict of Heywood. It stands close to the southern highway and is easy to identify from the surrounding roads, but most of the building is not normally open to V. In the base game, H3 functions primarily as a landmark, a fast-travel destination and a piece of environmental world-building rather than a fully explorable interior.

The building’s restricted state is part of its identity. The wider Night City directory classifies H3 as “open, temporarily closed”, distinguishing it from fully accessible buildings such as V’s Megabuilding H10 and from quarantined or construction-site megabuildings elsewhere in the city.

Although the exterior suggests a self-contained city block with housing, shops, access roads and internal infrastructure, the normal player route ends at the sealed entrance. The main exception is Gig: Hacking the Hacker, but that mission takes place in Megabuilding H6 in Arroyo, not H3. Confusing the two is one of the most common location errors in guides and searches.

District and subdistrict

Megabuilding H3 belongs to The Glen, one of Heywood’s subdistricts. It should therefore be treated as part of the Glen’s wider urban environment rather than as a separate district or as an extension of Wellsprings, Vista del Rey or Santo Domingo.

The building occupies a conspicuous position beside the highway system south of central Heywood. Its location is especially visible when travelling between the Glen’s inner roads and the southern approaches towards Santo Domingo. The road layout, ramps and raised structures make H3 appear embedded in a larger transport interchange, even though the game does not provide a normal route through the building itself.

Fast travel

The simplest route is to select Megabuilding H3 from the map once the fast-travel point has been discovered. H3 is listed among the Heywood fast-travel locations.

On arrival, V appears outside the megabuilding’s restricted approach. The dataterm is useful as a travel anchor, but it does not indicate that the building’s interior is open.

Driving route

The exact driving approach can vary depending on which road or ramp V uses. The important navigation cue is the building itself rather than a shop sign or mission marker.

When approaching by car

1. 01
   Enter The Glen from the northern or central Heywood roads.
2. 02
   Follow the raised highway and local access lanes towards the H3 marker.
3. 03
   Watch for the large megabuilding structure and the surrounding road barriers.
4. 04
   Leave the vehicle near the marked fast-travel area or roadside access point.
5. 05
   Continue on foot towards the front entrance to inspect the closure.

On-foot route

From nearby Heywood streets, follow signs and map markers towards the H3 dataterm. The exterior is difficult to mistake once the building is in view. The front approach is marked by a closed-off entrance, barriers and security or police activity. The normal game route does not offer a door prompt leading into a public lobby.

---

Main entrance

The principal entrance is the most important accessible part of H3. It is visibly designed as a functioning megabuilding entrance, but in the game’s normal progression it is closed. The closure is reinforced by physical barriers and the surrounding security presence.

The entrance should be understood as environmental scenery with restricted access, not as an undiscovered shop district waiting for a keycard. There is no verified base-game progression step that opens H3 for ordinary exploration.

Confirmed exterior directory

• Megabuilding H3

Roof, internal floors and hidden geometry

Players have used exploits, glitches and free-camera techniques to look beyond the normal entrance. Video demonstrations show attempts to enter through restricted areas, access garage-like spaces or move through the building’s central geometry. These demonstrations are useful evidence that H3 contains substantial modelled or partially modelled structure, but they do not establish ordinary gameplay access, functioning services or a complete interior layout.

For a standard playthrough, treat such areas as:

A player who reaches an internal space through a glitch may find incomplete geometry, inaccessible lifts, empty rooms or areas without normal collision and quest scripting. Those spaces should not be presented as fully supported subareas.

---

Confirmed services

The only clearly supported standard service associated with H3 is its fast-travel dataterm. The location’s exterior does not provide a confirmed vendor, ripperdoc, weapon shop, clothing shop, food vendor, apartment terminal or vehicle service.

Unconfirmed or unsupported claims

The following should not be listed as H3 facilities without direct in-game evidence from the relevant version:

These services are associated with the general megabuilding concept, and some are explicitly found in other megabuildings such as H10. H10’s documented layout includes apartments, parking and service areas, while its broader database description mentions shops, market stalls, a gym and a shooting range. That information belongs to H10 and to megabuildings in general, not automatically to H3.

---

Residents

No named H3 resident has been firmly established in the accessible base-game content. The building is visually presented as a residential megabuilding, but the player is not given a normal resident directory, apartment access route or set of named tenants.

It is therefore safest to distinguish

Security and law enforcement

H3’s temporarily closed state is communicated through restricted access and police or security presence. This is a location condition, not a separate faction-controlled interior district.

The visible personnel should not automatically be labelled as a permanent H3 corporate security force. The game does not clearly expose a unique H3 security faction in the same way that some missions identify gang, corporate or private military occupants.

Factions

No gang headquarters or faction-owned compound is confirmed inside H3’s ordinary playable area. In particular, H3 should not be confused with Megabuilding H6, where 6th Street occupies a mission area during Hacking the Hacker. The H6 mission guides identify that location as an Arroyo megabuilding and describe a 6th Street hideout reached by lift and upper walkways.

No confirmed H3 interior mission

The base game does not provide a verified standard mission that sends V through H3’s normal entrance and into an explorable H3 interior.

This point is important because search results for “megabuilding mission” often lead to Hacking the Hacker. That gig is set in Megabuilding H6, Arroyo, despite some search snippets and player discussions referring only to “the megabuilding”. Its objectives include entering the building, reaching the upper floor, infiltrating a 6th Street hideout and uploading a virus. The listed rewards include eddies and experience, but none of that belongs to H3.

Activities at H3

There is no verified fixed collectible route, vendor loop or repeatable combat encounter tied specifically to H3’s exterior.

---

The practical activities are limited

1. 01
   Discover the fast-travel dataterm.
2. 02
   Inspect the closure and building exterior.
3. 03
   Use the location as a visual landmark when navigating The Glen.
4. 04
   Photograph or study the architecture and surrounding road system.
5. 05
   Explore only through normal routes unless deliberately using non-standard glitches.

Fixed items

No confirmed named weapon, iconic item, shard collection, cyberware cache or unique clothing reward has been established as part of the normally accessible H3 exterior.

The building’s inaccessible status means that claims about loot in hidden floors require especially careful checking. A video showing an object model or a lootable container through a glitch does not prove that the item is intended for standard acquisition.

Nearby fast-travel context

The Heywood fast-travel network includes H3 alongside a range of nearby points such as Glen-area stations, roads and civic or commercial landmarks. The exact nearest point depends on the route and version of the map, so players should use the in-game map rather than assume that every nearby dataterm belongs to H3.

Nearby-location directory: For a normal base-game visit

1. 01
   Fast travel to Megabuilding H3.
2. 02
   Face the megabuilding and identify the restricted front approach.
3. 03
   Walk around the exterior far enough to understand how the highway and access lanes frame the building.
4. 04
   Check the entrance for environmental details, barriers and security activity.
5. 05
   Avoid treating blocked doors or collision gaps as progression routes.
6. 06
   Use the map to compare H3 with H2, H6 and H10, but do not merge their interiors or missions.
7. 07
   If researching the building for a completion guide, record H3 as a landmark and fast-travel point rather than as a conventional dungeon or commercial hub.

Practical checklist

---

Megabuildings were designed as dense, vertically organised residential environments. Their purpose was not simply to provide high-rise flats, but to combine housing with many of the services needed to support a population inside one enormous structure. General setting material describes apartments of varying quality, integrated entertainment and communications, commercial hubs, parking and hired security.

H3’s closed exterior creates an interesting contrast with that ideal. It looks like a complete urban ecosystem, yet the player experiences it as a sealed and controlled structure. That presentation fits one of *Cyberpunk 2077*’s recurring themes: Night City is full of systems designed to serve the population, but access to those systems is uneven, conditional and often controlled by authorities or corporations.

The building also helps establish The Glen’s scale. It is not merely a street-level neighbourhood of bars and side roads. The district contains enormous residential infrastructure, stacked roadways and landmarks that dominate the skyline. H3’s role is therefore primarily visual and spatial rather than mission-driven.

---

The general 2077 megabuilding directory lists H3 as “open, temporarily closed”, while H10 is presented as V’s megabuilding and has a documented accessible layout including apartment and parking areas.

---

Practical checklist

Does H3 ever open later?

There is no confirmed normal story progression that permanently opens H3 for free exploration in the base game. Its closure should not be treated like a temporary early-game lock that disappears after completing a particular main job.

Can H3 be entered?

Players have demonstrated non-standard entry methods using glitches, collision gaps, free-camera movement or other exploits. Those methods are not equivalent to intended access and may vary by patch, platform and game version.

Is Hacking the Hacker in H3?

No. It is in Megabuilding H6, Arroyo, Santo Domingo. The mission’s references to a megabuilding, elevator and 6th Street hideout are the source of much of the confusion.

---

Where is Megabuilding H3?

It is in The Glen, Heywood, in the southern part of Night City.

Is Megabuilding H3 open?

The building is classified as open, temporarily closed, but the player cannot normally explore its interior. The exterior and fast-travel area are accessible.

Is there a shop inside?

No standard, confirmed shop is available to V in the normal H3 exterior area.

Can I buy an apartment there?

No purchasable H3 apartment is confirmed in the base game.

Is there a hidden mission inside?

No confirmed ordinary H3 interior mission has been identified. Hacking the Hacker is in H6, not H3.

Are the police outside hostile?

The closure and security presence are environmental features. Hostility can depend on player actions and the game state, so they should not be treated as a dedicated H3 combat encounter.

Is the interior cut content?

The building has enough visible and glitch-accessible geometry to suggest that more of it was modelled than the normal game exposes, but the available evidence does not establish exactly what was planned, cut or merely created for skyline and environmental purposes. It is safer to describe the interior as restricted or unused rather than definitively calling it cut content.

The following could not be established confidently from reliable accessible evidence:

Accordingly, this guide does not claim that the exterior directory is an exhaustive catalogue of every modelled asset inside the megabuilding. It is a guide to the verified, standard-access H3 location in the Cyberpunk 2077 base game.
