+Antorum Online is a micro-multiplayer online role-playing game by [@dooskington].
+The game server is written in Rust, and the current "official" client is being
+developed in Unity. The server can be self-hosted, and the network protocol is
+open, so even custom clients that adhere to the protocol can connect and play.
+
+Two more devlogs were published this month, regarding work done to implement
+shops, character creation, and a few other features:
