Microsoft has unleashed its finest legal hounds against the owners of the domain name Halo4beta.net.

The move comes after David Ellis, creative director of 343 industries, through his Twitter account warned that this website, which claims to allow sign up for Halo 4 beta, is fake. Apparently Microsoft has filed a complaint witt the National Arbitration Forum. But the operator appears to have shut down the website.

It looks like Microsoft did not consider the move enough and is starting to apply the legal thumbscrews. Most people think that Microsoft will be successful in pursuing the National Arbitration Panel to order the transfer of the name.

In June 2011 Microsoft acquired the domain name Halo4.com paying an undisclosed amount. Halo 4 will be in the shops for the Xbox 360 by the end of 2012.
