Ninja Katana is currently not available on Armor Games.
We are using Ruffle to emulate Flash content, but it doesn't currently work for all games.
Over time, we expect more and more Flash games to be playable again.
Thank you so much for all of your years of support and enjoyment!
In the meantime, please enjoy the below selection of HTML-based games and Ruffle-emulated Flash games that also will rock your socks.
Please see our news post for more information: The Future of Flash on Armor Games.
