Despite the fact I got my Hydra ready in time, Monday's campaign game was an unmitigated disaster. Long story short, far more Skaven turned up than I expected and a Dwarf force less than a quarter the size of the other two forces managed to win by hiding up in a Watchtower and shooting anything which came near. I conceded 1870 victory points whilst only scoring 320 of my own.
I think my problem came (aside from being thoroughly out-pointed and suffering from terrible dice luck) from having too many monsters and not enough ranked units.
Luckily, it's simple enough to fix that, so I've started batch painting the Corsairs which have been sitting in a box in my gaming cupboard for ages.
I've only done the basecoat for now, but I'll be adding washes when I get home later. The fun bit is going to come once they're finished and I can start magnetising the bases and building the magnetic movement tray to go with them.
