In the PC version of the game, a player can earn Making Popcorn by simply vanquishing enemies as the Drone, without actually using the Corn Strike.
This is quite easy to get, as it is a total overall, not ten with one Corn Strike. It is best to aim at teleporters or gardens that are being captured in Gardens and Graveyards, as they are where you will get the most vanquishes with the Corn Strike. Some other ideas would be to use it at choke points in Team Vanquish, retreating zombies or spawn points. This is easier to achieve with the Garlic Drone than the Artichoke Drone because the Garlic Drone deploys more corn.
