The update means Apex Legends, Dead By Daylight, and Halo multiplayer should all work on the Steam Deck at launch.

And it gets better: Easy Anti-Cheat doesn't just offer native Linux support now, but also support for Wine and Proton, the compatibility layers used to run Windows applications on Linux. Proton is what Valve is using to make the entire Steam library playable on the Steam Deck, even though relatively few games have native Linux ports.
"Starting with the latest SDK release, developers can activate anti-cheat support for Linux via Wine or Proton with just a few clicks in the Epic Online Services Developer Portal," the update reads.
Epic made Easy Anti-Cheat a free service this year, meaning we're likely to see more of it in future online games. But it's already a pretty big name—here are some of the Steam games that should now be playable on the Steam Deck at launch, assuming anti-cheat was the only thing holding them back.Apex LegendsBlack Desert OnlineDauntlessDead By DaylightFall GuysHalo: The Master Chief CollectionHunt: ShowdownKnockout CityPaladinsWarhammer: Vermintide 2
