About Lethal Geometry
You don't build towers. You build the machine that carries one laser beam: mirrors bend it along the enemy path, splitters fork it, lenses on the trunk make it stronger. Some enemies fight back with geometry: an Armored one soaks up most of the beam, a Reflector's front shield stops it cold. The whole defense is the shape of the light.
