Phantom Protocol

Phantom Protocol is a sci-fi dating sim for players who like harem stories with a moody, watchful undertone. It plays quieter than most sandbox adult games, favoring caution and control over comedy.

Story

In a world ruled by Phantoms, the protagonist learns to stay unnoticed and follow the rules set above him. When circumstances shift, his place in that order changes, pulling him closer to people like Renee and Charlotte, and to someone from his own past he didn't expect to see again.

Gameplay

Play moves between school-life scenes and free-roam exploration, where choices shape how each relationship develops. Conversations, small decisions, and recurring encounters build trust with the women around the protagonist, while occasional gameplay mechanics break up the routine of dialogue and exploration. Progress is paced through story events tied to specific characters rather than open-ended grinding.

Features

• 3D-rendered characters and animated scenes throughout
• A school setting layered with sci-fi and hidden-power elements
• Multiple character-specific storylines developing in parallel
