Battlefield 6 has been partially compromised by the piracy group RUNE, allowing players to access a pirated version just over a month after its official release. This version is in a Portable format, requires no installation, and takes up about 100 GB of storage. It only includes the single-player campaign with nine missions, while multiplayer functionality is not available. A "free week" event for multiplayer will occur from November 25 to December 2 on Steam and consoles, featuring maps like Siege of Cairo, Eastwood, and Blackwell Fields, and game modes such as Conquest, Breakthrough, Team Deathmatch, Sabotage, and one unannounced mode. Battlefield 6 is not available in the Russian region, and accessing it on Steam requires a foreign account and a different region's IP address.
