That place the portal takes you, will be there forever. Eternal agony never dissipates. Feel the fury of a 1000 oinks!
I wish zombie pigmen were hostile all the time. -.-
So that unless you were on peaceful, there was absolutely no chance of surviving in Hell at all? :tongue.gif: Zombie Pigmen are pretty tough, and with entire armies being aggroed to you as soon as you step foot in Hell? No thanks.
If you just mean you want Hell more Challenging, remember that it was pretty much just added, I'm sure there will be new mobs added in the future. (Possibly along with new blocks)
