About Creeper World

Better described as tower offence than tower defence. A bit like a cross between Perimeter (2) and Harvest: Massive Encounter.

Essentially you're fighting against an infinite flood of goo with guns (lasers, mortars and such) rather than building barriers with the sole aim of connecting "totems" (usually submerged in the "creep" by the time you reach them) to open a warp portal to the next world. Occasionally there's side objectives.
