This is one of two of the pics that I drew which you will find in the new Mutants and Mastermind Gamemasters Guide!!
Yup, I actually have work in the MM GMG, I was honoured to be asked to do this and am very very proud of how this turned out. The deadline was tight but I got this one to look almost exactly how I wanted it to look.
So what're you still doing here, go get yourself a copy and see for yourself, and tell them you want more of my work in their books
You can order and/or get the pdf version here [link]
Oh, no they're not fighting each other, the one in the suit without an arm is getting knocked by the werewolf looking guy into the hoodie zombie. But I can see how they look like they're fighting.
One minor quibble: the zombie in the orange hoodie and the one missing an arm seem to be fighting each other. What's up with that?
