It's available for preorder - go check it out. The PDF and Hardcopy combo are $49.99. The PDF alone is $15. I think I would want both in this case. As I've said in earlier posts, it appears this will be a nice way to had some layers and chrome to your quick playing Battletech Alpha Strike games.
You can access information and purchase links on the Catalyst Game Labs Battletech blog on the Alpha Strike Companion.
