+_Two clients connected to the same server_
+
+[Arcana] is ECS based game engine focused on simplicity and performance.
+
+It recently got huge progress towards multiplayer support.
+Traditional client-server systems were added and used in the ["Tanks" example][arcana-tanks].
+
+Clients send only command queue to the server and server sends game world updates
+to the clients. Engine supports multiple players per client.
+For example players may be added for each active input device.
+
+To allow wide variety of genres player is not attached to one specific entity
+and may control many.
+In RTS player may control all their units and will send commands for each one.
+
+Gameplay system that consumes commands doesn't even need to be aware of netcode.
+Either way it just drains command queue of an entity and utilizes them.
+That system must not be run on clients at all.
+
+[Arcana] is very early work-in-progress and may not always work
+out-of-the-box atm, but stability improvements are expected next month.
