We are definitely aware that much of what makes the Wing Commander franchise great and memorable are the supplementary materials, subtle winks to past iterations of the game, and unique presentation of a "manual" in the style of claw marks, etc.
I can assure you that there is something in the works, that will be available here and it's really faithful to the spirit and presentation of those materials you remember and love!
This is more fantastic news for WC fans. From Claw Marks to the Secret Ops website, the additional fiction available for previous games has been an important bonus component to the overall experience, and it's great to hear that this effort is being made here. XBLA games traditionally have just a few pages of basic instructions in-game, so it seems that Arena continues to raise the bar in terms of what Live Arcade games have to offer.
