So maybe not Lego...this set was released last year by a company called Best Lock. The blocks work with Lego and Mega Bloks...well they should, I haven't tried it yet. But it was a pretty cool set. I haven't opened it yet.
It is a product I never would have expected to get released but it is a lot of fun, especially since it involves the futuristic fighting briefly shown in the Terminator movies.
