@supersmashchar My strat for all Frostbite always starts this way. Let's call C9 the column closest to home and the rows 1 - 5 from top to bottom.
PS - C8 R1
PS - C9 R2
FP - C8 R2
From then on I plant PS on all the back (C9 & C8 back WHiTE squares and FP on the BLACK squares starting with the middle 3 rows. R2 - R4. Now all of your Primal Sun stay nice and toasty warm and in this level in particular, you've covered the squares all zombies are forced to by the gates. Once you have this basic layout, you're unbeatable.
