Saw these today.
The vehicle and figs are quite large.
The vehicle is pretty neat. Figs are so-so. They offer only a few Colonial Marines that I saw, one guy who looks like he's in a space suit, and three alien poses, plus a face-hugger jumping out of an egg (that was pretty neat). There's also one very large, alien too, which looks to be the "Queen", or "boss", if you will. Perhaps there are, or will be other packs with the other Marines or characters from the movie, Aliens.
$15 for the vehicle, and $10 for the figure packs, which include two figs each, and/or a sentry gun and an alien. A decent value, especially for kids, as long as they don't get nightmares from the creatures.
