Mirage: Arcane Warfare, the fantasy follow up to Torn Banner Studio's insanely popular Chivalry: Medieval Warfare, is about to be shut down for good thanks to new European Privacy laws coming into effect today, May 25, 2018. Thankfully, Chivalry will not be affected.

Yesterday, Torn Banner released a statement on their forums announcing that the game was being removed from Steam and all third-party retailers and the multiplayer servers would be shut off on May 31. The reason, the post explains, is due to General Data Protection Regulations (GDPR), a stricter enforcement of privacy laws in Europe that is creating trouble for more than just games.
