Today we have released an updated version of our RuneScape Windows client.
Use of this alternative client is entirely optional, and it doesn't add any extra features compared to playing through your web-browser at our website like normal. It does however allow you to play without all that browser clutter, which is particularly useful for low-memory or low-resolution machines.
The client can be found in the new Extra Files section on the front page. Unofficial downloads from other sites may contain malware, so to keep your account safe we recommend you only get the client from www.RuneScape.com
