EXTRA: Pako Battiliar Achievement in Vampire Survivors

This is cumulative over all runs of all levels played, and you can check your status in the Unlocks menu. Personally, I apparently had this many bat kills already, but I also spent time beyond achievements playing for fun. If you don't have this achievement, you can grind it out on most maps, but there isn't a way to know you've gotten enough kills until the run ends. Loading up the first map, Mad Forest, with Endless, Hurry, and Hyper turned on, along with playing as Sigma, is an easy way to idle for this achievement. Get all of your strongest weapons and items, max them out, evolve them, then choose random upgrades for Limit Break levels, and you can set your controller down and rack up kills.
