Hopper Invasion, the intentionally laggy, straight up unfair and clunky mod you'll ever see. This mod will start the invasion of alien hoppers, that grow and multiply with each kill. After some time they'll start to infect the ground, and and drop your tps to a crawl, the only way to stop this is to kill the Mother Hopper, if you even dare to challenge the nest.
The mod is in active development, if you want to know when the versions are coming out or what is planned check out my server https://discord.gg/6mJaYSTcBq
