I wouldn't mind army building Firefly but seeing as how there are going to be great army builders in the Shock Troopers and the Jungle Vipers, I better hold off. If the jungle coverings are removable, then I'll want even more of those Vipers.
I'm so thrilled with the POC figures I have that I'm actually considering getting a HISS.
I highly recommend the HISS! I absolutely love the design, it's very well engineered and put together, has a ton of detail, and I was totally surprised at how huge it turned out to be once I got mine assembled! I still can't fully grasp how they got all that plastic to fit into such a tiny box. I have to say that I think this may actually be one of my favorite all-time Joe vehicles in this size range!
