Hey, I was just wondering, how do you think difficulty will be judged on Portal? Assuming they have Easy Normal and Hard.
I can only imagine that the combine balls will last not so long, but I can't see that making the game harder as they respawn anyway.
Most of the destruction and damage in the game is physics/impact based so theres no health or weapons involved
Maybe you die easier by the turrets or something?
I'd like to hear views.
