Today shall see the release of several Halo Fleet Battles extras from Spartan Games. Extra dice are available as are commander packs. A Large Battle Group upgrade is available for both the Covenant and the UNSC forces, these packs have 2 Heavy cruisers and a few escorts in the shape of Corvettes and Frigates depending on which race you play.
How ever for only an extra five pound you can get Covenant Core Battle Group or the UNSC Core Battle Group which in the case of the UNSC the number of models jumps from eight to twenty eight models, which is an absolute bargain.
Also in the Core Battle Groups you will receive overlays for 3 new formations for each faction.
