No Fungus Among Us Achievement Guide
Starting The Level
So I recommend that you have already beaten adventure mode. Now you have to do it again until you get to level 2-1 (First level of Night mode). From There Chose these Plants: Kernel Pult, Wall-Nut, Sunflower, Potato Mine, Squash and then add every other explosive you prefer Apart From Doomshoorm.
Sunflower And Potato Mine
Now for this part, first plant a few sunflowers until the zombies start coming. then when the first zombie comes put a potato mine to kill him and start placing more sunflowers and repeat until two zombies start coming at once.
Kernel Corn Defense
After that start placing a kernel corn at a zombie and a potato mine at the other. Keep repeating that until you have a full row of kernel corns.
From here you can place another row of kernel corn a place some other explosives and defenses.
And from here you are pretty much done and you can claim your achievement.
