TL;DR
As of July 28, 2026, ProtonDB rates Palworld Platinum and rates Halo: Campaign Evolved and Shift At Midnight Gold for Linux and Steam Deck play [1]. Those ratings suggest all three can run through Proton, but only Palworld reaches the community tier associated with working cleanly out of the box across tested Linux setups.
Three of today’s most-watched Steam games can run through the Linux compatibility technology behind Steam Deck, but they do not arrive at the same starting line. On July 28, 2026, Palworld holds a Platinum ProtonDB rating, while Halo: Campaign Evolved and Shift At Midnight sit at Gold [1]. That difference can separate a quick launch from an evening spent changing settings.
This guide shows you what those ratings mean, where ProtonDB and Valve’s Deck labels differ, and how to check a game before spending your money. You will also get a practical setup routine for handling updates, controller quirks, and performance limits without treating every stutter like a disaster.
The ratings here form a date-stamped compatibility snapshot, not a permanent promise. A game patch, Proton release, anti-cheat change, or SteamOS update can move the ground beneath your feet like a loose floorboard. Use this briefing as your map, then check recent reports for your exact Deck model and software version before you install 60 GB over a slow hotel connection.
Choose Palworld first when you want the strongest ProtonDB result in this three-game snapshot; it is Platinum on July 28, 2026.
Treat Halo: Campaign Evolved and Shift At Midnight as promising Gold-rated choices, then read recent Deck-specific reports for any required tweak.
Do not translate ProtonDB Platinum into Valve Verified or ProtonDB Gold into Valve Playable; the two rating systems use different checks.
Before traveling, test a demanding scene, suspend and resume, controller input, audio, and an offline launch on your own Steam Deck.
Attach a date, Deck model, game build, SteamOS version, and Proton version to every performance claim you trust.

The Three Games You Can Put on Your Deck Shortlist
Steam Deck compatibility looks encouraging across all three highlighted games on July 28, 2026: Palworld leads with Platinum, while Halo: Campaign Evolved and Shift At Midnight carry Gold ProtonDB ratings [1]. None falls into the lower Silver, Bronze, or Borked tiers in this snapshot.
- Palworld — Platinum: The community rating points to the smoothest Linux setup of the group. If you want to download a game before a long train ride, this is the strongest candidate for launching without compatibility work.
- Halo: Campaign Evolved — Gold: The game reportedly works well through Proton, though some Linux users may need a tweak. Check current reports for campaign videos, controller prompts, online features, and the Proton version used.
- Shift At Midnight — Gold: You can expect a workable Linux experience based on community testing, but Gold leaves room for a launch option, alternate Proton build, or small display adjustment.
Think of the tiers like traffic lights with extra shades. Platinum gives you a bright green signal, while Gold tells you the road is open but may contain a rough patch. In a real living-room scenario, Palworld may launch from the sofa, while a Gold game could send you to Desktop Mode for one quick fix.
These are ProtonDB community ratings, not promises of a fixed frame rate, battery duration, or official Steam Deck verification. Performance can differ between the original LCD Deck and Steam Deck OLED, and it can change with the selected resolution, power limit, game patch, SteamOS build, and Proton release.

See the Compatibility Differences at a Glance
Steam Deck compatibility is strongest for Palworld in this July 28 comparison because its Platinum tier sits above the two Gold results. Halo: Campaign Evolved and Shift At Midnight remain solid candidates, but their ratings tell you to read recent user reports before relying on them away from home.
| Game | ProtonDB tier | What the tier suggests | Your smart next check |
|---|---|---|---|
| Palworld | Platinum | Reported to work cleanly through Proton without game-specific changes across qualifying reports | Check recent Steam Deck performance reports and installation size |
| Halo: Campaign Evolved | Gold | Reported to run well, with tweaks sometimes needed | Check campaign playback, online services, controls, and current Proton versions |
| Shift At Midnight | Gold | Reported to run well, though a setting or workaround may be required | Check text size, controller prompts, video playback, and launch reports |
Suppose you have 90 minutes before boarding a flight. The table tells you to try Palworld first, but it does not replace a launch test. Start the game, load a real save, enter a busy area, suspend the Deck, wake it, and confirm that sound and controls return normally.
The two Gold entries are not poor choices. Gold often means the game itself runs well while one stubborn detail rattles in the background, like a loose coin in a dryer. A community-recommended Proton version may fix that detail, yet online modes and anti-cheat systems deserve their own check because they can behave differently from a single-player campaign.

What Each ProtonDB Tier Tells You Before You Buy
Steam Deck compatibility tiers on ProtonDB summarize community reports about running Windows games through Proton on Linux. Platinum is the strongest result, Gold usually means good play with possible tweaks, and the lower tiers signal growing friction. Borked means the game is effectively unusable under the reported conditions [1].
- Platinum: The game works cleanly out of the box in qualifying reports, without game-specific changes.
- Gold: The game runs well, but you may need a small adjustment such as choosing another Proton release or adding a launch option.
- Silver: The game is playable, though issues can affect comfort, features, or reliability.
- Bronze: The game runs, but frequent or serious problems make the experience hard to recommend.
- Borked: The game fails to start or cannot be played meaningfully under the tested setup.
Imagine testing a Gold-rated game after dinner. The title screen appears, the controller works, and the opening level moves smoothly, but a cutscene shows colored bars instead of video. That is the sort of specific flaw hidden inside a broad tier, which is why the written reports matter as much as the medal.
A tier also combines reports from many Linux systems, not only Steam Deck hardware. A Platinum desktop result does not promise that the Deck’s AMD Zen 2 and RDNA 2-based APU will hold your preferred frame rate, while a Gold rating does not mean poor handheld performance. The tier answers whether the game works through Proton, not how cool, quiet, or long-lasting your portable session will be.

Avoid the Mistake of Treating Gold as Valve Playable
Steam Deck compatibility has two rating languages: ProtonDB community tiers and Valve’s official Verified, Playable, Unsupported, or Unknown labels. A ProtonDB Gold result does not automatically mean Valve Playable, and Platinum does not automatically mean Valve Verified. Each system measures compatibility through a different process.
Valve’s Deck program checks handheld details such as controller input, readable text, default settings, and whether you must use an on-screen keyboard. ProtonDB collects real user reports from Linux hardware and distills them into tiers. One system acts like a formal inspection sticker; the other behaves like a busy noticeboard covered with fresh field reports.
For example, a game may run perfectly through Proton and earn Platinum on ProtonDB, yet still miss Valve Verified status because tiny menu text becomes hard to read on the Deck’s 7-inch or 7.4-inch display. The opposite kind of mismatch can happen when Valve’s test remains published while a new game update creates a problem that users report soon afterward.
Community compatibility and official Deck status answer different questions. Check both before buying a game for a trip, especially when you need offline play, readable text, or dependable controller support.
You should also check the regional age rating and store warnings when buying for a younger player. Compatibility only tells you whether software works; it says nothing about suitable content, online chat, user-created material, or in-game purchases. The Steam store listings for all three games provide the current product details available in your region [2].

Four Checks That Prevent a Bad Handheld Session
You can turn a promising rating into a dependable session by checking recent Deck-specific reports, testing the game’s demanding moments, confirming suspend behavior, and keeping one known-good Proton setup. This four-step routine catches the problems that a single compatibility badge cannot show before you leave reliable internet behind.
- Read reports from the last few weeks. Filter for Steam Deck hardware when possible, then note the SteamOS version, Proton release, game build, and whether the report covers single-player or online play.
- Test beyond the opening menu. Load a crowded settlement in Palworld, a combat-heavy Halo checkpoint, or a dark effects-heavy scene in Shift At Midnight. Menus place far less pressure on the Deck than smoke, enemies, reflections, and streaming scenery.
- Test suspend and resume. Play for 10 minutes, press the power button once, wait a minute, and wake the device. Listen for crackling audio and check whether controller input, network access, and frame pacing return.
- Keep notes on a working setup. Record the Proton version and the two or three settings that matter. If an update causes trouble, you will know what changed instead of twisting every dial at once.
For a concrete travel test, unplug the Deck and disable Wi-Fi before launching. A game that works beside your router may hit an account login, cloud-sync warning, or online authentication wall on the train. Offline testing exposes that trap while you still have time to fix it.
Change only one setting at a time. If you switch Proton versions, lower every graphics option, install Proton GE, and add three launch commands together, you will not know which change helped. A tidy test takes longer at first, but it leaves you with a clear trail of breadcrumbs when the software shifts again.
Why a July 2026 Rating Can Change Under Your Feet
A July 28, 2026 compatibility rating is a snapshot because game patches, Proton releases, SteamOS updates, graphics drivers, launchers, and anti-cheat rules keep moving. Your installed game can work on Tuesday and stumble after Wednesday’s patch, even though the store page and community tier have not yet caught up.
Compatibility has several layers stacked like a tall sandwich. The game sits on Proton, Proton sits on SteamOS, and SteamOS talks to the Deck’s hardware. When one layer changes, the whole stack can wobble. A harmless launcher redesign on Windows, for example, can become a blank login window on Linux.
This timing problem also affects search results and automated answers. If an AI service says its knowledge cutoff in October 2023 means it does not have access to specific articles published after that date, it cannot independently confirm a July 2026 status. Use dated ProtonDB reports and current Steam listings instead of treating an older overview as live evidence.
The best habit is simple: check the reporting date, game version, Proton version, and hardware named in any performance claim. A statement such as smooth performance means little without those details. A useful report says it came from Steam Deck LCD or OLED, names the software build, describes the tested scene, and identifies the frame-rate target.

Frequently Asked Questions
Is Palworld fully compatible with Steam Deck in July 2026?
Palworld holds a Platinum ProtonDB rating in the July 28, 2026 snapshot [1], which is the strongest community tier. That rating says the Windows game works cleanly through Proton across qualifying Linux reports, but it does not promise a fixed frame rate, battery duration, or Valve Verified status on every current build.
Does ProtonDB Gold mean a game runs badly on Steam Deck?
No, Gold usually means the game runs well but may need a tweak. Halo: Campaign Evolved or Shift At Midnight could launch and play normally for you, while another setup needs a different Proton version or launch option. Read the written reports to find the exact issue behind the rating.
Are ProtonDB ratings the same as Steam Deck Verified labels?
No, the systems are separate. ProtonDB summarizes community Linux reports with Platinum, Gold, Silver, Bronze, and Borked tiers, while Valve uses Verified, Playable, Unsupported, and Unknown labels for its Deck review program. Check both labels and their dates because each reveals different details.
Can I run Windows games on Steam Deck without installing Windows?
Yes, Proton lets many Windows games run on SteamOS, the Linux-based operating system shipped with Steam Deck. Steam usually applies Proton automatically when needed. You may sometimes choose another official Proton release or community-maintained Proton GE, but changing versions can create new quirks as well as fix old ones.
What should I check before taking a Steam Deck game offline?
Launch the game with Wi-Fi disabled, load a real save, play a demanding scene, and test suspend and resume. Confirm that cloud-sync messages, account checks, or launchers do not block access. A 10-to-15-minute offline test at home can save an entire flight from becoming a staring contest with an error box.
Conclusion
Your clearest choice from this July 28, 2026 snapshot is Palworld, but the badge should begin your check rather than end it. For any of the three games, spend 15 minutes testing a real save, suspend and resume, and offline launch before you depend on it away from home.
Compatibility is wet paint: patches and Proton updates can change it while the label still looks settled. Check the date, read the newest Deck reports, and test your own machine. Then, when the train slips into a tunnel and the Wi-Fi icon goes dark, your game should keep glowing in your hands.
