  • Quick Answer: Assassin's Creed Black Flag Resynced will be Steam Deck Verified when it launches on July 9, meaning Ubisoft has designed the remake to meet Valve's compatibility standards from day one. The Steam release will also include full Steam platform features, including achievements, trading cards, badges, profile backgrounds, and emoticons.

With more AAA games making their way to handheld PCs, Steam Deck compatibility has become almost as important to some players as console support.

Ubisoft is clearly aware of that demand, announcing ahead of launch that Assassin's Creed Black Flag Resynced will be Steam Deck Verified on day one.

By working to meet Valve's compatibility standards from the start instead of after release, the publisher says the remake will be Steam Deck ready on July 9.

What Does Steam Deck Verified Actually Mean?

Steam Deck Verified is Valve's highest compatibility certification for games available on Steam.

To earn the badge, a title must meet several requirements, including full controller support, readable menus and text on the handheld display, proper launcher behavior, and an overall experience that works without requiring players to manually adjust controls or troubleshoot compatibility issues.

Although the certification doesn't guarantee a specific frame rate or graphics preset, it is intended to reassure players that the game has been tested specifically for Steam Deck.

Ubisoft says its goal was to make Black Flag Resynced feel equally enjoyable regardless of where players choose to play.

Whether players experience Edward Kenway's adventure on a desktop PC or on the go with a Steam Deck, Ubisoft says both versions are designed to deliver a comparable experience.

The announcement also confirmed that Steam users will get full Steam platform integration on day one.

Players will be able to unlock Steam Achievements as they progress through the game while also collecting trading cards, profile backgrounds, badges, and emoticons that tie into Steam's community features.

These additions may not change gameplay, but they help the Steam release feel like a complete PC version instead of a basic storefront port.
