King Arthur's Gold is a free online action game developed and published by Transhuman Design for Windows, Mac and Linux.

[1] King Arthur's Gold (often abbreviated and referred to as KAG) is a game about mining resources, building castles and destroying the player's enemies.

Total conversion mods also exist, e.g. Shiprekt where players build ships from blocks in a top-down view arena.

A few heads are recognized by modded, unofficial, and official games (multiplayer and singleplayer), but those are specially-earned, usually by being part of the development team of King Arthur's Gold.

The team of THD started working on KAG (King Arthur's Gold) on 18 April 2011,[3] and the first alpha version was released only 3 days later.
