Erohazard is a 2D adult RPG made by w0wthatscool in RPG Maker. It is a parody of Biohazard, with turn based combat and CG artwork. You play a male agent during a zombie outbreak in Tanuki City, teaming up with Clara and other recognizable characters. You fight zombies, hellhounds, lickers, and other monsters while moving through the police department and other city locations. The story focuses on building relationships with your partners.
The current build is v0.8, released on May 27, 2023 for Windows and Mac in English. Development is ongoing, with planned updates adding new characters, enemies, CG, relationship options, puzzles, endings, and costumes. Version 0.8 gives all characters costume changes in the NG+ store, adds an Annetta ending, and fixes bugs. The game is uncensored.
