This really is a great game. I intended to pick it up last year but forgot all about it. I recently got it on iOS and that prompted me to buy the board game.
I've played it duo and solo and tried out a fair few of the pawn colour combos. I'm finding it easiest using the pilot and the messenger as a team, (using iOS as a gauge here too...it's harder on that platform) The Engineer's pretty pumped too. As a character the diver looks to be a bit weak at the moment.
I've had some tense games, sitting out on a couple of tiles hoping for a chopper card. Plus, I've lost twice in 10 games by turning over Waters Rise and Fool's Landing in the first hand...bad luck.
Success rates have been high on novice so it's time to move onto normal I think.
I'm keen to try out the other map configurations (available on the web), which should and some flavour.
As said above, it is a good solid game and well worth the investment.
