March of Giants Steam Deck: Handheld Play Explored

Why Everyone Is Asking About March of Giants Steam Deck Support

March of Giants Steam Deck support is one of the first questions players ask about Ubisoft’s upcoming free-to-play 4v4 MOBA — and right now, there is no confirmed answer. Valve’s compatibility program still lists the March of Giants Steam Deck status as Unknown, which means the entire conversation is built on system requirements, anti-cheat behavior, and informed speculation rather than a green Verified badge.

That matters because this isn’t a small indie release. March of Giants is a free-to-play, team-based strategy game from Ubisoft where you command a towering Giant and rally hundreds of Soldiers across lanes. It’s the kind of pick-up-and-play multiplayer game that handheld owners naturally want on a couch, a commute, or a lunch break. Knowing whether it will actually run — and whether it will run well — saves you from wishlisting something that may never leave your desktop.

What Valve’s Compatibility Rating Actually Says

Here’s the short version: the Steam page shows Steam Deck Compatibility: Unknown. That’s not the same as “Unsupported.” It simply means Valve has not finished (or published) a Deck review for a game that hasn’t launched yet.

The single biggest signal here is the operating system line. The store page lists Windows 10/11 64-bit for both minimum and recommended specs, with no Linux or SteamOS entry. On its own that’s not fatal — plenty of Windows-only games run beautifully through Proton — but combined with kernel-level anti-cheat, it becomes the central question.

Easy Anti-Cheat Is the Real Gatekeeper

Easy Anti-Cheat is one of the most common anti-cheat solutions on Steam, and it can run under Proton. The catch: it only works on Linux/SteamOS when the developer opts in and ships the Linux-compatible EAC module. If they don’t, the game will launch and then immediately refuse to connect or close itself.

For March of Giants, that choice sits entirely with the “March of Giants Team” and Ubisoft. There’s no public statement yet confirming Linux support, which is why the compatibility field remains blank rather than optimistic.

Community reports from other EAC-powered online titles suggest a familiar pattern: single-player or casual modes sometimes slip through, while ranked and competitive modes stay locked down. Given that March of Giants is explicitly built around online PvP, online co-op, and esports-style taglines, expect the anti-cheat gate to be strictly enforced. If you’re buying a Deck specifically for this game, wait for an official statement rather than a hopeful Reddit thread.

March of Giants System Requirements vs. Steam Deck Hardware

Let’s compare what the store page demands against what a Steam Deck actually delivers. This is where the picture gets more encouraging than the anti-cheat question.

The honest read: the Deck’s 16 GB of RAM matches the recommended memory target, but its GPU sits below the listed minimum card. The minimum spec is also explicitly tuned for 1080p at 75% render scale and low settings — and the Deck renders at just 1280x800, which is roughly half the pixels. That resolution advantage is exactly why so many “below minimum” games still hit 30–40 FPS on Deck.

If March of Giants scales its Soldier rendering well (hundreds of units on screen is a CPU-bound problem, not purely a GPU one), the Deck could end up in a comfortable “Playable” tier rather than a slideshow.

Expected Performance Scenarios on Steam Deck

There is no public build to benchmark, so treat the table below as a planning estimate based on the requirements and typical Proton behavior, not a measured result.

Two practical notes. First, cap your framerate. A 40 FPS cap with a 40 Hz refresh is dramatically smoother than an uncapped framerate bouncing between 30 and 55. Second, expect the Soldier system — hundreds of units, pathfinding, and Battleworks placement — to stress the CPU more than the GPU. Lowering graphics settings won’t fix CPU-bound dips during massive clashes.

How to Get Into the Playtest and Test It Yourself

The game is not yet available on Steam, but the developers are running a Pioneer Playtest. Here’s the practical path if you want to be an early handheld tester.

Also worth doing before you spend an evening troubleshooting: check a community Proton report database for the app ID once playtests go live. Player-submitted reports usually reveal within 48 hours whether a title boots, plays, or is blocked by anti-cheat.

Live-Service Realities That Affect Handheld Play

Even in a best-case scenario where March of Giants runs flawlessly through Proton, a few design choices will shape how good the handheld experience feels.

• Always-online requirement. The store page states a persistent internet connection is required. No offline practice against bots on a flight.
• Competitive pressure. A 4v4 MOBA with hundreds of Soldiers and Battleworks placement is a high-APM, high-information game. Reading lane states on a 7-inch screen is harder than on a monitor.
• Controls. Steam Deck’s trackpads and back buttons can map mouse-and-keyboard style inputs surprisingly well, and gyro assists with precise targeting. Expect to spend real time in the controller configurator.
• Battery life. Large-scale battles with hundreds of units will drain the Deck faster than a turn-based game. Budget roughly 1.5–2.5 hours of unplugged play.
• Text and UI scaling. Accessibility features on the store page cover camera comfort, custom volume controls, stereo sound, and playability without quick-time events — but no handheld-specific UI scaling is mentioned.

If you plan to play mostly docked with a controller, most of these concerns shrink considerably. If you want true handheld competitive play, temper expectations.

Quick Verdict Table

The one thing that would change everything is a Verified badge or a developer comment confirming Linux/EAC support. Until then, wishlist it, request playtest access, and keep an eye on the Steam page.
