Forge World, like the rest of the stuff for 40k, has updated their model’s stats for 6th edition. You can get the updates as downloads from their site.
On this page you will find various PDF files you can download completely free. Downloaded files can be stored on your computer for easy off-line reference or printed out on your printer. The rules presented here are Experimental rules, still under development, and are not the final version. Experimental rules will change over time before a final version is published.
