New ways to deal with enemies, be it attack or defense.
turret shield tech need 1,2,3+mil pack to research. but after making defence line. turret hp is not important anymore. maybe bit earlier and cheap research to get benefit early?
i really don't know, but you can just toggle research off and on whenever you like
better now? base = 2 bottles x 75 upg 1 = 4 bottles x 200 upg 2 = 6 bottles x 300 upg 3 = 2^(0-x) space x 500
