Monster Girl Invasion is a JRPG style Adult game featuring monster girls.


The first Early Access Alpha version of Monster Girl Invasion RPG is now released!

The game is effectively still an alpha and does not fully represent our vision for the final version, however we hope it is in a state that is both playable and enjoyable for players!



Travel across a dangerous world filled with frenzied monster girls suffering from a virus which makes them attack men and become sex crazed. 

Humans live in fear, conflict happens often and monster girls invade towns and villages to attack the men. Any man that fails to protect himself and is 'finished' by a monster girl contracts the virus and becomes her slave until she either uses him up or kills him/eats him.

Monster girls are ostracised from society, even those who are not infected. Forced to live in secret and with a human civilization hungry for revenge, war brews on the horizon.

One young man discovers he has the special power to cure this disease in monster girls and embarks on a treacherous journey, risking becoming a victim himself.

With his party of allies and cured monster girls, he attempts to set the wheels of change in motion and fix this broken world.


The gameplay consists of classic JRPG style familiar to those who enjoy old school games of the genre.  During your adventure you will get into battles with monster girls where they will either try to KO you or seduce you, if you lose they violate you, if you win, you may be able to convince them to join you.

  • 22+ Different Monster Girl Types (More to be added in updates)
  • Varied H-Scenes featuring monster girls
  • Classic JRPG Combat with many classes and abilities
  • A large world to explore with many secrets
  • Recruit monster girls and create a party unique to your playstyle

We would like to include a large variety of monster girls where possible and interesting scenarios when the player loses. We endeavour to update the game frequently with story content as well as new scenes. 

We are working with our artists to create a game that you will hopefully enjoy and find enticing.
