The HTML5 client for Achaea is in open beta, and all players are invited to give the new client a test. The new client has many features like recording gameplay with real-time playback, lots of scripting support, and gameplay in general feels much smoother on the client. The Achaea forums have also been given a tremendous makeover, and users are now required to log in using their character name. No more anonymous forum trolling!
As you can see from above screens the HTML5 client is much fancier, has a larger screenwidth and is much more customizable compared to the old Flash client below.
Of course playing MUDs through your browser is just one option, many players like to download the free MUD client called Mudlet, or a paid one like Cmud, and you can download lots of MUD scripts from Iron Realms for your favourite MUD games.
