Good news! It does! My desktop was out of commission for a while due to a hardware issue, and I used my Steam Deck exclusively as my PC during that time. Hunt ran fine, with anti-cheat working, and I even racked up some kills and wins (with mouse and keyboard and a monitor ofc and at 720p). The handheld experience would be rough but obviously playing Hunt against PC players with a controller would be nearly impossible in 3 star and up.
