Sudden Strike 5 is the latest WWII real-time tactical strategy game from Kite Games and Kalypso Media. It just released today and it's even Steam Deck Verified.
Valve's testing with the current stable Proton 10.0-4 notes that everything should work as expected, apart from external gamepads not being automatic so you may need to swap them around in the quick access menu. Hopefully the developers actually tweaked
From the press release: "Sudden Strike 5 unleashes a slew of new features and quality-of-life upgrades over its predecessor, designed to give commanders more control and tactical choice. Players can construct bridges over rivers to open new routes to catch enemy forces by surprise, call-in reinforcements via sea or railroad, and coordinate large-scale maneuvers with improved visibility and streamlined unit management, allowing for the deployment of overwhelming force!
Take control of the battlefield in one of three major factions: the Western Allies, Soviet, or Axis forces, across an expansive 25-mission campaign. From the frozen landscapes of the Eastern Front to the harsh deserts of North Africa, each battlefield presents unique challenges demanding careful planning, adaptability, and tactical mastery."
