Hi folks - while finishing the AW expansion, I ran into the big Devil-dude at the end. How the hell do you kill it? I was hitting it with bullets, rockets, even slicing-and-dicing and using cow-heads, but nothing seems to be working.
What obvious thing am I missing?
[BTW, Apocalyspse Weekend is NASTY, especially on the 'Manic' setting I am using]

If I remember correctly that guy has things floating around him.
Shoot those things with pistols.
When they're all gone, use rocket launcher on the devil.
After some time those flying things come back and you have shoot them again in order to be able to damage that devil.

Many thanks, HertogJan - you were right.
I shot all the little flying globes and was then able to damage the beast; then the globes came back while I was busy trashing some zombies the beast has called up - boo!
I will have to improve the accuracy of my pistol shooting before i actually successfully complete this, but at least I know that I can finish it now.
Once again, thanks!
Problem solved!
