Only four sculpts. They're just minions, though.
* One minion holding an axe upwards with two hands.
* One minion holding an axe upwards, but with ONE hand.
* One minion holding an axe, but
TO THE RIGHT!!!
* One minion NOT holding an axe and just the shield. OMG
WTF BBQ!!!
Minions have the same gameplay, so the various minion sculpts don't really do more for me than the various Zombicide walker sculpts. Maybe, since there's a timer, Riot found were they to have minions with different gameplay, the game didn't play as well as having all minions play the same.
The minions are unpainted but have a wash, so you can see the details when you hold them up close. But, assuming you'll be moving the minions with your hands and not your nose, all the sculpts all sorta look the same on the board unpainted. (So paint them!)
One also nice thing about the tray is that the wells are not sculpt specific! You can put any minion miniature in any minion well. Take that, CMON!
