Mythica was a never-released massively multiplayer online role-playing game (or "MMORPG") based on Norse mythology. It was under development by Microsoft Game Studios (MGS) for Windows-running PCs until it was cancelled in early 2004. The game had been under development for over two years and had a development staff of forty at the time of cancellation.
As with most MMORPGs, one would have needed to purchase the game software and then subscribe to the game service, paying a monthly fee. The combat design was centered on being a demi-god, including the ability to swat waves of enemies aside to focus on their boss.
