NieR Automata Ver1.1a is not the game you played. The title itself gives it away, that "Ver1.1a" tag tacked onto the end like a version number for software. Yoko Taro didn't just put that there for style points. It marks this anime as a separate branch in the Drakengard multiverse, a timeline where things go differently from the 2017 game. If you approach this expecting a shot-for-shot recreation of 2B and 9S's journey, you're going to get confused when Eve dies before Adam, when Lily leads the Resistance instead of Anemone, or when the whole geography of the ruined world shifts around to connect locations that stayed far apart in the PlayStation version.

I keep seeing people complain that the anime "changed things" as if that's a mistake. The changes are the point. Taro supervised this personally, co-writing the scripts with Ryoji Masuyama specifically to wreck the original story structure. There's documented evidence of the production staff fighting to preserve game accuracy while Taro pushed to blow it up. The result sits somewhere between adaptation and alternate universe fan fiction, and that's exactly what makes it worth watching even if you've memorized every ending from the game.

The Route Merge Problem

The biggest structural hurdle any NieR Automata adaptation faces is the game's multiple route system. You play through the story first as 2B, then as 9S, seeing the same events from different angles while the game hides critical information from you until the second playthrough. An anime can't do that without boring viewers to death with repeated scenes.

Ver1.1a solves this by running both perspectives simultaneously. Instead of Route A followed by Route B, you get both threads woven together in real time. When 2B fights machines in the desert, the anime cuts to 9S hacking the network to support her. When 9S discovers something disturbing during a side mission, we see his reaction right away instead of waiting hours for his dedicated route to start. This creates a more cohesive narrative but loses some of the game's disorienting effect where you realize halfway through that you didn't understand what was happening the first time.

The pacing moves fast, sometimes too fast. The anime covers roughly one in-game chapter per episode during the first cour, sprinting through locations that gave players time to breathe and absorb the atmosphere. The amusement park, the flooded city, the factory, they all flash by with machine efficiency. A-1 Pictures clearly struggled with the sheer volume of content they needed to compress into 24 episodes, and you can feel the rush in certain episodes where emotional beats don't get enough room to land.

A2 Gets the Development She Deserved

If there's one thing the anime absolutely fixes from the game, it's A2's characterization. In the original NieR Automata, A2 shows up relatively late, acts angry, fights you, and dies unless you pick her ending. Her backstory exists only in text logs and a stage play most players never see. She's supposed to represent the tragedy of YoRHa's prototype models, but the game barely gives her screen time to sell that weight.

Ver1.1a dedicates significant runtime to the Pearl Harbor Descent, adapting the stage play and manga that explain who A2 was before she became a deserter. We see her as No. 2, optimistic and trusting, leading her squadron into a suicide mission that Command planned from the start. We watch her bond with Lily, the only survivor, and understand exactly why she hates YoRHa so much. When she finally meets 2B and 9S in the present timeline, her hostility makes sense. She's not just a random antagonist anymore. She's a traumatized survivor who watched her friends get sacrificed for data.

The episode focusing on this backstory, directed by Toshimasa Ishii, stands as the highlight of the entire series. It justifies the anime's existence better than any other sequence. Without needing to read external materials or hunt for lore documents, anime-only viewers understand A2's motivation completely. The anime even gives her more time at Pascal's village, showing her softening before the tragedy hits, which makes her eventual fate hit harder.

Character Swaps and Death Changes

The anime swaps who lives and who dies in ways that fundamentally alter the political landscape of the Resistance. In the game, Anemone leads the Resistance camp and survives until the endgame. Lily dies during the Pearl Harbor flashbacks. Ver1.1a flips this. Anemone dies during the descent mission, and Lily takes over as leader in the present.

This isn't just cosmetic. Lily carries survivor's guilt from watching Anemone die, and her leadership style differs from Anemone's calm authority. She knows A2 personally from the descent, creating a connection that didn't exist in the game. When the virus hits the camp in the anime's second cour, Lily's death carries more weight because we've spent time watching her lead, watching her struggle with the responsibility Anemone left her.

The Adam and Eve timeline gets messed with too. In the game, 2B kills Adam in theCopied City, and Eve goes berserk with grief. In the anime, Eve sacrifices himself to save Adam, dying in Adam's arms instead of fighting the androids. This sends Adam into a completely different character arc. Instead of dying peacefully, he survives to become a mindless monster, transforming into something resembling the grotesque designs from NieR Reincarnation. The anime removes the Grun boss fight entirely to make room for this altered Adam storyline, which some fans miss but others find more interesting than fighting another giant machine.

Geography and World Building Shifts

The anime plays fast and loose with the map of the ruined world. In the game, Pascal's Village sits deep in the Forest Kingdom area, requiring a significant journey to reach. In Ver1.1a, the village sits right behind the commercial facility shopping mall. The forest exists as a separate location accessed through different means, and the missing sister side quest redirects there instead of leading to the desert.

These changes compress the world for narrative convenience, but they also create weird implications. The anime includes a hidden church in the Copied City, a direct nod to the infamous sadfutago mod that went viral before the anime aired. 9S hacks into Emil's memories and sees visions of NieR Replicant characters like Kainé and Yonah. Emil's head gets stuck in a tree in Pascal's village where the machines worship it as a religious icon.

Spatial inconsistencies pop up everywhere if you look too close. The flooded city appears at different times. The tower shows up early as background imagery. Some viewers theorize these aren't just production shortcuts but hints that the anime world literally differs from the game world on a fundamental level, possibly running on different server architecture or existing in a simulation with different parameters. Given the game's themes of reality being questionable, these changes might be intentional meta-commentary rather than adaptation errors.

Production Woes and Visual Quality

Nobody can talk about Ver1.1a without mentioning the delays. The series started in January 2023, went on hiatus after episode 3 due to COVID affecting the staff, came back, then went on another hiatus before finishing the first cour in July 2023. The second cour aired in 2024, completing the 24-episode run.

These delays show in the final product. The premiere episode features rough 3DCGI for the flight units and machines that looks janky compared to the smooth 2D character animation. Action sequences sometimes lack the fluidity you'd expect from a flagship adaptation. Still frames replace motion during busy moments. The art direction remains gorgeous, capturing the melancholic color palette of the game perfectly, but the movement doesn't always match the beauty of the backgrounds.

A-1 Pictures did nail the character designs, though. 2B and 9S look exactly like their game models but adapted for 2D animation. The Pods float with the right weightless quality. When the animation works, like during the A2 flashbacks or the final confrontation in the tower, it really works. But consistency issues plague the series, especially during the first cour where you can almost see which episodes got finished before the hiatus versus after.

The Original Ending Alternative Eden

The final episode, labeled "[E]nd of YoRHa" but subtitled "Alternative [E]den," diverges completely from the game's Ending E. Instead of the Pods reconstructing 2B and 9S's data after the player deletes their save file to help a stranger, the anime gives us a concrete continuation where A2 fights 9S in the collapsing tower.

A2 accepts the machine network's offer to join their spacefaring ark but dies as the structure falls. 9S tries to kill 2B one last time in his corrupted state. The Pods rebel against their programming to defend the androids' bodies, getting destroyed in the process. Then, in a post-credits scene, we see 2B and 9S wake up together in a peaceful field, implying the Pods succeeded in rebuilding them despite sacrificing themselves. Accord from the Drakengard series makes a cameo, suggesting she repaired A2's body too.

This ending combines elements from Routes C, D, and E but creates something new. It gives closure to the A2 vs 9S conflict that the game left ambiguous depending on player choice. It confirms survival for the main trio without requiring the meta-commentary about player sacrifice. Some purists hate this, arguing it undermines the game's bleak tone. Others appreciate that the anime, as a separate timeline, gets to explore what if things ended less tragically.

Why It Works as a Companion Piece

Ver1.1a isn't trying to replace the game. It can't. The game relies on player agency, on the guilt you feel when you realize 2B has been killing 9S repeatedly, on the frustration of the bullet hell hacking sequences that mirror 9S's deteriorating sanity. An anime viewer passively watching these events doesn't get the same psychological impact.

But the anime does things the game couldn't. It shows you A2's past without requiring you to buy a stage play Blu-ray. It lets you see 2B and 9S interacting during downtime that the game skipped. It adds the YoRHa Dark Apocalypse lore from Final Fantasy XIV and references NieR Reincarnation's mobile storyline. Commander White gets more characterization, showing actual concern for her units instead of cold detachment. Even the Operators 6O and 21O get expanded roles before their tragic ends.

The post-credits scenes shift format between cours. First cour uses creepy live-action puppets acting out the game's joke endings. Second cour switches to Pod 042 and 153 having philosophical discussions about the nature of their observations. These segments reward longtime fans with deep cuts while staying accessible to newcomers.

If you played the game, Ver1.1a offers a fresh take on familiar events, a "what if" that respects the original while doing its own thing. If you never touched the game, the anime serves as a solid, if compressed, entry point to the franchise. Just don't expect it to hold your hand through the lore. The show assumes you're paying attention, and it rewards that attention with details like the hex codes hidden in eyecatches that translate to lore documents.

NieR Automata Ver1.1a stands as proof that game adaptations don't need to be slaves to their source material. By embracing its identity as a separate timeline, it tells a story that complements the original rather than competing with it. The changes aren't accidents. They're deliberate choices that expand the multiverse Yoko Taro has been building since Drakengard. Whether you think those choices improve the story or dilute it depends on how attached you are to the game's specific beats. But you can't say they played it safe.
