Worm Nest Plague is a 2D animated RPGM game by ST Hot Dog King, set in a microscopic world where you play as a parasite. The goal is to infect a host and rebuild your colony, collecting and crossbreeding pathogens to strengthen your battles. Its fantasy and transformation themes shape the microscopic setting and encounters.
Development is finished, and the current build is v1.02, dated June 9, 2024, for Windows, Android, and Mac. The release includes the final boss fight and final ending scene. It is in English and uncensored. The v1.02 update added a random debuff during fights, cheat items to add or remove visual debuffs, or make every enemy pregnant, and restored the T3 affection event replay. It also fixed bugs in the TP module and standing animation updates.
