Can anyone tell me what comes in the 2 player battlebox?

I have yet to see one anywhere. I know it is a random 2 factions from the Rise block but beyond that I'm not clear.

Is it non-randomized within a specific faction, so every box with a GUARD army has Defender X (or whoever) and a specific list of units or is that random as well?

What about buildings? Are they random or a specific set? If the later what are they? Or are the buildings specific to the factions too?

What maps come with it? Block War and Smashville again?

Like I said, I keep hearing that the 2-player battle boxes sold really well, but I have never seen one, and I don't think my local store is able to get them (he has ordered them every week for the last 3 I think and they don't show up).

I'm just curious what comes in them.

From reports I've read:

Most boxes contain 2 random monsters from different factions, supported by Rise units for those 2 factions. The units seem to be standard, that is, no variation within a faction between monsters, with equal distribution among rarity class...the same number of common/uncommon/rare per faction. Buildings vary, but most came with 1 of each of the 9 Rise buildings, while some were reported to have only come with 6, as is printed on the box.

Each box also comes with 2 sets of dice, 2 life trackers, 1 rulebook, and the Smashville/Block War map.

Monster pairs do appear to be random, so you can get Defender X against Gorghadra in one box, and Goghadra against Zor Raiden in another.
