Nier: Automata Steam Install Size Reportedly Swells to 366GB After Language Update

Nier: Automata appears to have developed a remarkably large storage problem on PC. Following a Steam update that adds Simplified Chinese, Traditional Chinese, and Korean language support, attempts to reinstall the action RPG are reportedly being met with a required disk-space figure of 366.56GB. That is a startling rise for a game whose Steam system requirements still recommend just 50GB of available storage.

The apparent jump is especially puzzling because the update itself seems relatively minor. Its published notes list the three newly supported languages and do not indicate that new game content, a major technical overhaul, high-resolution asset package, or other substantial addition has been introduced. Early observations likewise suggest that the game itself is otherwise unchanged beyond the welcome localization options.

For a title originally built around a compact but densely layered action RPG experience, a 366GB installation would be an exceptional demand. It would place Nier: Automata among the most storage-hungry PC games available, despite its original 2017 release and a long-standing 50GB requirement. The discrepancy has understandably led players to question whether the figure represents an accidental packaging issue rather than the intended new footprint of the game.

A small patch with an outsized installation requirement

The patch in question is dated November 6, 2026 and expands Nier: Automata's language support on Steam. Simplified Chinese, Traditional Chinese, and Korean have been added, making the acclaimed RPG more accessible to a wider group of players. Localization updates matter, particularly for a story-heavy game with multiple endings, extensive dialogue, text-based lore, weapon stories, and systems that invite repeat playthroughs.

Yet language support alone would not normally be expected to multiply a game's installation size more than sevenfold. Audio files, subtitles, interface text, and localized materials can add meaningful weight depending on implementation, but the leap from roughly 50GB to 366.56GB is far beyond what players would associate with three added languages.

Reports indicate that the update download itself has been far more ordinary, with some Steam users seeing a download of around 8GB. That contrast is one of the key details in the situation. An 8GB patch may be sizable, but it is plausible for a game update that includes new localized assets. A Steam client asking for hundreds of gigabytes to complete an installation is another matter entirely.

It is possible for download size, unpacked installation size, and temporary space required during patching to differ substantially. Steam sometimes needs extra room to stage files while it replaces or rebuilds existing game data. Even so, the reported 366.56GB requirement is so far above Nier: Automata's listed needs that it has raised the possibility of duplicated files, incorrectly assigned depot data, or an archive and compression failure.

Steam's listed requirements have not caught up

As of the reports surrounding the patch, Nier: Automata's Steam store page continues to state that players need 50GB available space. That unchanged listing further supports the idea that the massive number may not be intentional. If the publisher had genuinely increased the game's permanent storage requirement by more than 300GB, the minimum and recommended specifications would normally need an immediate update.

There is no indication in the brief patch notes that an enormous asset expansion was planned. No new campaign, new visual mode, overhaul of cinematics, remastered texture suite, or bundled collection of additional games has been announced as part of this particular update. The core game appears to remain the same Nier: Automata experience players know, now with expanded language options.

That leaves a technical explanation as the most likely answer. Players have speculated that portions of the game may have been included repeatedly in files associated with downloadable content or other Steam depots. Another possibility is that Steam is calculating installation or temporary extraction space incorrectly because of how the updated package was assembled. Neither explanation has been confirmed.

Whatever the exact cause, the size shown during installation should not be confused with proof that Nier: Automata now contains 366GB of distinct playable material. At present, the evidence points to an unusually large reported space requirement following a small patch, not to a deliberate addition of hundreds of gigabytes of new content.

Why a packaging issue can create huge numbers

PC game installations are made up of many moving parts: executable files, compressed archives, texture and sound packages, language data, redistributables, DLC files, manifests, and platform-specific delivery rules. A problem in any one of those areas can produce results that seem absurd from the player's perspective.

For example, an update system could potentially treat existing archives as new files instead of replacing them. A depot configuration might point to content that was not meant to be included in the public installation. Duplicate archive references could result in Steam reserving extra capacity. During decompression, a platform may also request space for both older and newer versions of files at once before deleting the originals.

Those possibilities are general examples rather than a diagnosis of this particular update. Without an official explanation, it is impossible to say whether Nier: Automata's unusual Steam requirement is caused by duplicated data, a manifest issue, an error in space calculation, or something else entirely. The important point for affected players is that the game's own storefront requirements and the reported installation prompt currently do not align.

Storage demands have become an increasingly important concern for PC players, especially as modern releases regularly exceed 100GB and some large games push beyond 200GB with high-resolution textures, expansions, and optional content packs. A 366GB demand for Nier: Automata would be significant even on spacious modern SSDs, and could make a reinstall impractical for players using smaller drives.

What players can do while waiting for clarification

Players who have Nier: Automata already installed may want to avoid deleting it solely to perform a clean installation until the discrepancy is clarified, particularly if their available disk space is limited. Those who have encountered the 366.56GB requirement can also keep an eye on Steam's download behavior, installed-size readout, and future client updates, as these details may help establish whether the issue is temporary or limited to particular configurations.

• Check the free space on the drive where Steam is installing the game.
• Compare the download size shown by Steam with the amount of disk space requested for installation.
• Review the game's Steam news and update notes for any follow-up patch.
• Use Steam's file verification tools only with awareness that the process can itself require temporary space.
• Wait for an official statement or corrective update before assuming that 366GB is the game's intended permanent requirement.

It is also worth remembering that the affected update adds language support that many players have wanted. Simplified Chinese, Traditional Chinese, and Korean support is a meaningful improvement for an RPG whose narrative and tone are central to its appeal. The problem is not the addition itself, but the apparently disproportionate storage behavior that has accompanied it.

An odd technical twist for a celebrated action RPG

Nier: Automata remains one of the most distinctive action RPGs of its era, blending PlatinumGames' fast, stylish combat with a story designed by director Yoko Taro that shifts perspective, structure, and genre as players progress. Its long afterlife on PC has included both continued player interest and periodic discussion around technical support, making any new Steam update notable.

This latest situation is notable for a less glamorous reason: an apparent installation number large enough to invite disbelief. The patch notes could hardly be more straightforward, yet the reported storage requirement suggests something much bigger happened behind the scenes. Until the publisher or developers explain the change, players are left with a mismatch between an 8GB-scale update download, a 50GB store-page recommendation, and a reinstall prompt asking for 366.56GB.

For now, this looks less like a surprise expansion for Nier: Automata and more like a deployment issue in need of a fix. Players seeking the new language options should watch for further updates, especially if Steam continues to require hundreds of gigabytes for a game that has historically occupied a fraction of that space.
