Spartan Games posted up their Firestorm Armada rulebook on their website as a free .pdf download. Why not grab yourself a copy?
From the announcement:
The Firestorm Armada setting has huge potential as a setting for space combat, and it is a perfect platform for using the fantastic models produced by our creative design team in a fun game that lasts just a few hours.
The rules allow a small skirmish, involving just a few models per side and only two players, to be played as easily as a massive game between space armadas that could easily contain several large Capital Class vessels, hordes of smaller vessels and with several players per side commanding the fleets.
Now, for the first time, we’re offering the Firestorm Armada Rulebook available as a FREE download!
