Hmmm, there's a few things I like and don't like about the latest CC release.
Like:
Campaign mode looks fun. Not exactly sure how it will play out, but it looks fun.
Mines. As in, land mines. Since the only type that doesn't rely on an actor picking it up and placing it is the cluster mine-bomb, it's most useful type. It can also be used during the build phase to plant minefields.
Grapple gun. Haven't used it yet, but hell yes.
Don't like:
Campaign mode features no AI. Not really fun at the moment.
Drop area during skirmish mode reduced to a tiny area around your base/brain. Annoying, since you're supposed to be dropping this stuff from orbit, in stuff that flies(I use the term very liberally), so you should be able to drop it anywhere you need. Sure, it might be balancing for base-to-base fighting, but it shouldn't be for something like orbital artillery(aka "Rods Crabs of God". Yes, God has crabs)
Crab-bombs seem to be a whole lot less useful, and not just because the reduced drop range.
It seems a bit buggier, although I don't have much experience with the previous version(didn't have the registered version, anyway). Campaign mode has some bugs, and it crashed about 10-15 minutes in during Skirmish.
The three color-coded bombs have been replaced with a single bomb/detonator. While not terribly useful, it did allow more elaborate explosive design.
