Neon Abyss 2 Steam Deck: Verified, Settings, Co-op

Neon Abyss 2 is Steam Deck Verified, and unusually for a game this size the confirmation comes with numbers rather than just a badge. Steam Deck HQ's reviewer measured 90 FPS with under 10W of battery drain on Deck hardware, and a separate developer interview explains how the Verified badge was earned. The game also carries full controller support, including both DualSense and DualShock pads, so no touch-screen workarounds are needed.

Developer interview on Deck testing — Steam Deck HQ, August 6, 2025

• Steam Deck status: Verified, green badge (developers say they targeted Verified from day one)
• Measured performance: 90 FPS at under 10W battery drain, measured by Steam Deck HQ's reviewer
• Controller support: full, with DualSense and DualShock both supported
• ProtonDB rating: Platinum
• Caveat: the verification and the 90 FPS figure are both from the August 2025 Early Access period, not from 1.0

Is Neon Abyss 2 verified on Steam Deck?

Yes — and the developers have explained how it went, which is more than most Verified badges come with. In an interview about how the game was tested on Deck during development, Veewo said the team "did need a little bit more work than we thought" before they "got the charm green verified badge with another submission for review."

That is worth reading carefully, because it tells you the first attempt failed. The team had to resubmit. The takeaway for a player is that the green badge is a result that was earned through a second pass rather than something the game shipped with by default, and the game was being tested on Deck regularly throughout development rather than certified at the end.

Neon Abyss 2 is also listed as Platinum on ProtonDB, where the top community report reads: "The game works great right out of the box. Even the multiplayer works just as well as it does on Windows." Independent community confirmation agreeing with the official badge is a good sign for a game whose co-op is the main event — see our co-op guide for what that multiplayer actually involves.

How does Neon Abyss 2 perform on Steam Deck?

The one published figure is 90 FPS with under 10W of battery drain — and it is worth being precise about where it comes from. That measurement is Steam Deck HQ's own hands-on testing, not a number Veewo published. The developer interview published in the same piece covers the badge and the work behind it, but says nothing about frame rate or battery draw. For a 2D pixel-art run-and-gun, a reviewer's 90 FPS is a comfortable result and consistent with the game's light requirements — the PC system requirements page list a GeForce GTX 950 or even Intel HD Graphics 630 as the graphics floor, which is a very low bar for a handheld to clear.

The sub-10W battery figure is arguably the more interesting number. It means the game is not going to drain a Deck's battery quickly, which matters most for exactly the situation this game suits: handheld play in short sessions. The PC system requirements page shows how low the bar sits on desktop — a GeForce GTX 950, or even Intel HD Graphics 630, is the official graphics floor.

What did Veewo change to make the Deck version work?

Two concrete fixes came out of the Deck testing, both documented in the interview.

Video transcoding. Videos shipped in the game were re-encoded to WebM specifically so they would play correctly on Deck. That is a small thing that would otherwise have produced broken cutscene playback — the kind of issue that quietly costs a Verified badge.

Controller UI hints. The first Deck review came back as only Playable, not Verified, and the cause was controller UI hints — on-screen prompts that were not resolving cleanly under pad input. Fixing it took about two days of work, after which the resubmission earned the Verified badge.

There was also a company-level reason this was manageable. Veewo's first game shipped on Nintendo Switch, so the studio already had handheld experience and existing knowledge of Deck-style UI adaptation. That is why the remaining work was described as "a little bit more work than we thought" rather than a rewrite.

Does controller support work properly on Deck?

Yes, and this is the least ambiguous part of the whole story. The Steam store's own feature list — visible in the app details record — records full controller support for Neon Abyss 2, and explicitly names both DualSense and DualShock as supported pads. Nothing about Neon Abyss 2 on Deck is a keyboard-and-mouse game with a controller bolt-on.

That matters more than it might sound, because a run-and-gun with room layouts, randomised item drops and up to four players is a genre where fiddly UI gets punished quickly. The original controller-hints problem was caught and fixed in about two days, which suggests the team treats Deck input as a first-class case rather than an afterthought.

Frequently Asked Questions

Is Neon Abyss 2 Steam Deck Verified? Yes. It holds the green Verified badge, with 90 FPS and under 10W of battery drain measured on Deck hardware by a Steam Deck HQ reviewer. The verification is from the Early Access period, so 1.0 behaviour with four-player co-op has not been re-verified.

Does Neon Abyss 2 co-op work on Steam Deck? Community reports on ProtonDB say the multiplayer works as well on Deck as it does on Windows. The 90 FPS figure is one reviewer's single-player measurement, and Deck performance with four-player online co-op at 1.0 has not been separately verified.

What are the Steam Deck performance issues with Neon Abyss 2? None reported against the Verified build. The first Deck review came back only Playable because of controller UI hints, and that was fixed in roughly two days before the Verified resubmission.

Does Neon Abyss 2 support DualSense and DualShock? Both are listed as supported, alongside the game's general full controller support.
