For some reason I was expecting something more, something to jump out at me so I could say 'wow!' but these segments just 'extend' ones that are already there, I guess this is why they are at the price they are. Don't get me wrong, they are worth it as there are quarter (semi-semi?) circles and triangles from which you can now build interesting segment shapes, but if you're looking for a pack as 'exciting' as the other models packs prepare to be disappointed.
Here are some of the models from WW2 Platforms:
and here's a shot of (animated) lava in game.
Are they worth it?
Yes as you can now create interesting segments/ rooms and they can always be re textured.
