... Honest!
Heh. Looks like Amber let the cat... er, bug... out of the bag. Something tells me that Art and Kat have been blissfully unaware of what the girls and the Denizens have been up to down in the caverns.
Looking at the size of Amber's suit, I'm certain that it's more like a battlemech than a suit of personal armour. The head is the right size for her to be riding in it, Gundam-style.
Meanwhile, in the extreme foreground, the battle continues. Those look like rocket pods on Jade's shoulder-guards. So, Amber's running around with a pair of duel heavy lasers (at least, if they're not plasma accelerators) and Jade's firing off either rockets or light missiles. The property damage estimates keep going up. All I can say is that the Men from the Ministry cannot possibly miss this one. Could a visit from some bowler-hatted clean-up crews be that far off?
