I'm in the US so I'm sure that cut some of the time off. I don't have the packing list in front of me but it was mostly add on and bonus stuff I'm missing. US armored infantry and assault teams, the big artillery vehicle, and I think the Martian zombie troops. I got the plastic tanks and tripods, US infantry, HMG teams, BEF squad, rough riders, fleeing civilians, and Martian Drones.
I haven't put any plastics together yet but they look pretty good. The metals have a fair bit of flash on them and I noticed a couple of miscasts on the smaller parts but nothing major.
