Night mission concept art

Basically, you can't tell which creeps you're fighting until they enter in tower range. For increased difficulty (and a sense of realism), all towers' visible range during night missions is reduced by 30%. Either that, or all towers keep level 1 visible range, no matter how high they're upgraded. Dimumurray suggested a similar idea here.
