I do like these Big Gunz models.
They are very quick and easy to paint. I start off with black, then drybrush Tin Bitz, then a lighter drybrush with Boltgun Metal. Details are then picked out with yellow and red paint.
They recently took part in a game.
And they didn’t do too well… even with a 36″ range I was too often out of range. Also as an ordnance weapon I couldn’t fire at the Valkyrie which flew onto the table.
