I got mine along with my upgrade (I ordered the full version for a friend). It does not come in one box. It comes in two boxes, the base Attack! and the Attack! Deluxe expansion.
Well, I already ordered, so I guess I'll live with the two boxes. That's good news that you already got the full version, I put in an order with Eagle, but it still says pre-order, so was kind of hesitant since I may be moving in a little while to a (hopefully) bigger and better residence.
