There’s a 22 page set of demo rules which include the full movement, combat, wound, vehicle, explosive and flying rules, as well as enough Archetypes to build some characters and teams to test the new shiny out.
There’s also a draft copy of the 2nd Edition Special Abilities PDF, with a good selection of the skills & special abilities that’ll be available in 2nd Ed.
More later perhaps when I’ve had a chance to look it over properly and build a character or two! Short version is that I like what I see, lots of streamlining and good tweaks to an already great system.
Full release of the rules is pencilled in for mid-March, apparently.
