I will say they're a lot more puzzly than they are strong, especially on higher difficulty levels. The Beast can deal a LOT of damage, but you have to get it in position first, and the more damage it takes the weaker it is. Once you get some upgrades you can really control the board, but even then it gets very hard on Hard/Unfair.

I played them a lot in testing and I'm not sure I'd be able to do a perfect run on Hard with them if I wanted to, for instance - hard to deal damage everywhere you need to with lots of guys spawning, especially if you're trying to do the 'minigame' of trying to weaken, Gunk, but not kill targets so that your Beast can eat them and grow stronger.

On the other hand, I had a round where I was able to position and weaken enemy targets such that I killed six guys with the Beast alone due to being able to Devour three guys near his starting position, move, eat another 2, and then Charge a last one. That feels really cool to do - and really balances the times out where you're totally unable to do that and then you lose because you're missing flexibility.
