Turns the biters into a strategic challenge throughout the campaign. They will endlessly attack your bases and clearing them is not always practical.

Generates a moat around the starting resources to let you set up, but you'll have to venture beyond your safe haven to collect more resources and advance.

A map generator preset is created for the right amount of challenge.
Resources are further apart and more plentiful. Pollution spreads further. Biters nests are more dense.

Biters have been amped: faster, larger attack waves, multiply on death (optional), and scale organically with pollution.
