Who would of thought you'd be able to create a map using nothing more than
your browser? Well if you run
firefox you can create some maps with a few clicks using your browser at
Worldcraft Online. The project started about a year ago and not until recently we've been notified that it has been translated. The online interface will allow you to create CS 1.6 style maps.
Obviously you can only create basic things with this browser-editor, but it's pretty cool when you can map with just some simple point, click and drag commands with your firefox browser. Check it out,
here.
