Picked up 2 of these battle packs today since it seems to be the easiest way to get Snowies.
1) Minifigures: 2 Snowtroopers, 1 AT-AT Driver, and 1 Imperial Officer. The Snowtroopers are the same as found in the new Hoth "playset", Not sure why we have an AT-AT Driver outside of his vehicle, but a nice addition to this set. The helmet is brand new in that it has a notch at the back of the neck showing part of his head, and is a white version of the helmet found on the pilot of the TIE Defender. The Imperial Officer seems to have the same helmet as found on General Veers in the Motorized Walking AT-AT.
2) Vehicle and emplacement: This battle pack comes with a white version of the new speeder bike found in the Republic Dropship. However, instead of the rods use for the vanes found on the one in the drop ship, these speeder bikes use jousting lances. It also comes with a ground station that has a radar station for the Imperial Officer and a flick fire missle platform manned by the AT-AT driver.
3) Playability: The Speeder Bike swooshes well, and the emplacement is ok, but it doesn't seem like anything found on Hoth. Overall, another great little army builder from LEGO.
