I had searched through the forums, but I may have missed if this topic was already created, so I do apologize if so!
But, I had a nifty little idea about some sort of survival Mode.
Not too sure how the layout would go, but the general idea would be multiple sets of Emitters, that are timed to go off at certain intervals to make the round extremely difficult, quit even impossible. Not so much to win, but just to see how long a person could hold out before eventually being overwhelmed by the creeper waves.
I was playing Nazi Zombies on COD: BO and had my Creeper game on pause taking a momentarily stress relieving man-slaughter when this idea had come together as I glanced back between my computer and the TV.
The idea of a Non-winnable, never ending horde of Creeper that I must waste possibly hours to fight against, only to lose in one immense wave after another.. just gets me amp'ed up.
I've attempted making similar maps on CW, but they all lack a bit of luster. As I try to give myself every advantage by digging immense pit-falls I can simply clear with drones repeatedly, so I usually take control of every situation I make.
But I've tinkered around with the map editor and I've hidden the totems far out of reach behind my rows of timed emitters.. Watched as I took my ground, and eventually lost it. Achieving some effect of what I had hoped, but I know someone else could improve on this!
But I would really like to know what everyone else's perspective is on this idea!
