@xXFrozenChromeXx That's why I use Iron Maidens to climb up areas or protect myself against ZPGs, Super Ultra Ball, and Impkatas. Works a lot better than the regular Tallnuts if you ask me. I even use them to stop the AI zombies from advancing.

I agree on Potato Mines being more of a defense than rushing objectives, I do the same as most others when trying to capture the base as a group such as planting Potato Mines there. In Zombopolis where Zombot launches, I tried sneaking in where the Zombies spawn to plant Potato Mines right where they drop down. (It is possible since they don't have the out of bound danger zone)
But what can it be if planning to replace Potato Mines? It has to be a plant though, I don't even know if it's possible to do so. 😕
The Drone's Spike Shot in this game overheats too fast. (The Parrot Pal doesn't have trouble overheating as fast than Garlic Drone though, don't know why)
