Initially, reports said the vulnerability resided in Dark Souls 3.
On Sunday, Bandai Namco representatives said the company was removing PvP server play for Dark Souls 3, Dark Souls 2, and Dark Souls: Remastered as it investigated the reports.
The tweet also said that Dark Souls: Prepare to Die would be affected.
Few details are available about the Dark Souls vulnerability, so its cause is not immediately clear.Blue Sentinel, a community-developed Dark Souls mod designed to counteract cheats, has already introduced an update that mitigates attacks, but until Bandai Namco gives players the all clear, players are best off staying away from player-on-player gaming.
