Marvel RivalsAn Overwatch-style free-to-play hero shooter released in early December 2024 and includes all the typical major online gaming elements: an in-game store with skins and customizations, battle passes, and anti-cheating technology. While Proton, which makes the Linux-based Steam Deck capable of playing just about any Windows game, has come a long way in just a few years, its biggest blind spots are these types of online-only games, like Grand Theft Auto Online, Fortnite, Destiny 2, Apex Legends, and the like.
