You will never be the same again


Jump into a 3D world, full of cute monster girls in Monster Girl Island Prologue, now available on Steam for free.

Developed and published by Redamz, Monster Girl Island Prologue is a first-person adventure game where you mysteriously end up on an island of monster girls. This is an introduction to what the full release of Monster Girl Island will be and it can be played as a standalone experience.

You first wake up to a naked, human-like girl next to you. Just as she’s about to introduce herself, a dragon girl interrupts. The two of them battle and you suddenly wake up for a second time. Was that just a dream? This time you see a petite cat girl and a busty dark elf. They interrogate you about how you got past the human barrier to their island. After providing a vague explanation, they decide to keep you around even though they don’t completely trust you. Later on, the three of you find a girl collapsed on the island. It’s the girl from the fight. She knows your name, but not about any dragon girl. Who is she and what is going on?

In Monster Girl Island Prologue, you can meet different kinds of monster girls, such as mermaids, arachne, slimes, kitsune, elves, and more. Take up quests from the residents and explore the island to your heart’s content. There are multiple choices for dialogue and branching paths for events. Choices can be of four different colors to show how important your choice is and what it could lead to. Blue choices are normal, red is lewd, black ends relationships, and white has consequences. When you complete an event successfully, you’ll have the chance to ask her for a naughty reward. If you build up your relationship, you can even start dating them.
