The box was generally the same size as Game Workshop's Battle for Black Reach boxed set. The first thing I noticed is that the box was pretty heavy, so much so that I weighed it at just over 4 lbs. The box is wrapped in very heavy shrink wrap--much heavier than I am used to. I wonder if this is a New Zealand thing?
Opening the box, you can see that the sprues are in handy ziploc bags, which is a nice touch. Throw them away once you've build them, or you can use them to store counters or other bits later.
The vehicle detail (Shermans, Firefly tanks, and StuGs) was decent, but not as good as the tanks I've seen from the Plastic Soldier Company. Fully painted and on the table, however, these tanks should be perfectly servicable.
The pouch with the Pak 40s have some metal parts representing extra shells for the anti-tank guns, and in the bag there are also some small rare-earth magnets. I'm not sure yet what they are intended for, but to include them is a nice touch.
Overall I am very impressed with Open Fire!. It looks like a great introduction into the game, and could be played as a game in its own right. For what you get in the box, the price is too good to pass up. If you're interested in getting into World War II wargaming, this product is the ideal place to start.
