Once more, thanks everyone for comments and input. I think I'll get it at some point, but I'll get other stuff, first.
How Iron Zombies were upgraded in Wave 2? New cards? I find none in the download section...
On Avatars, I was believing they're planned to be released in Wave 3. It isn't so?
I already own the Seamus one, anyway, even if I don't have the crew, just because how awesome it is (plus, I could still use it in lots of other games, from In Her Majesty Name to Savage Worlds).
