Apex Legends works fine on my Steam Deck. It's awesome now that there's cross progression now finally across Steam, Playstation, Xbox and Nintendo. I had progress across all of them and it's all together in one account now.
I really enjoyed the last season of Fortnite. The OG season where they brought back the style and gameplay of how Fortnite was when it first launched its Battle Royale mode. The new season is very gimmicky and I don't like it. But my younger brothers and cousins love it. It would be amazing to be able to play with them on Steam Deck. If Apex can do it, so should Fortnite.
