Turrets get a warm-up period after being placed.
Mods introducing new content into the game.
New ways to deal with enemies, be it attack or defense.
Could u add research that allows to shorten the time a turret takes to warm up? would definitly be useful!
It could start at 30 seconds and eventually drop down to 0 as research progresses. By the time you unlock zero warm up you'll probably have better options for taking out nests and such.
