The developers of Apex Legends have announced that they're going to be blocking the game completely on Linux platforms including Steam Deck.
Our dev team wanted to provide a bit more context into this and share some of the decision-making process that happened along the way. As mentioned in our prior anti-cheat dev blog, competitive integrity is a top priority for our team and there are many ways in which we’re battling cheaters—this is one to add to the list. We remain committed to more regular updates on topics like this and appreciate your continued reports.
In our efforts to combat cheating in Apex, we've identified Linux OS as being a path for a variety of impactful exploits and cheats. As a result, we've decided to block Linux OS access to the game. While this will impact a small number of Apex players, we believe the decision will meaningfully reduce instances of cheating in our game.
Linux is used by default on the Steam Deck. There is currently no reliable way for us to differentiate a legitimate Steam Deck from a malicious cheat claiming to be a Steam Deck (via Linux).
