About this game
Heartlines is an FPS game where you control a character, and it heavily focuses on choices within dialogues. The main point of the game is to approach characters and talk to them. Your dialogue choices will influence future conversations and the overall direction of the game.
10 DAYS: THE SHADOW OF A LIAR
"Kill him, or I will drag you all to Hell."
It started with a dream. A being of blinding light, a voice that shook your very soul. It gave you a holy command... or so it claimed: "One of your five friends has been possessed by the Devil. Find them. Eliminate them within ten days, or I will cast every single one of you into the eternal fire."
But light can be the cruelest deceiver. As you roam the streets and visit the homes of those you once trusted, a terrifying question begins to haunt you: Is this "Angel" a savior, or the very monster it claims to hunt? Are you a hero, or just a pawn in a divine execution?
A Story Driven by Paranoia and Blood:
Trust is a Death Sentence: Walk the streets, enter their homes, and look into their eyes. These aren't just characters; they are people you thought you knew. Every conversation is a minefield of secrets, lies, and hidden agendas.
The Divine Threat: You aren't fighting for glory; you are fighting for your soul. The "Angel" watches your every move, threatening you with damnation if you hesitate. But can you kill a friend based on the word of a shadow?
Dialogue-Heavy FPS Mystery: Use your eyes and your ears before you use your weapon. In this psychological FPS, a misinterpreted sentence can be more fatal than a bullet.
10+ UNIQUE ENDINGS: YOUR FATE, YOUR CONSEQUENCES
The truth is a shattered mirror, and how you piece it together is entirely up to you. With more than 10 distinct endings, every choice you make ripples through the final outcome.
Will you unmask the "Angel" and break the cycle of lies?
Will you sacrifice an innocent to save your own skin?
Will you find the true possessed soul, or will you become the very evil you were told to destroy?
When the tenth day ends, the sun will rise on a world changed forever. The question is: will you be alive to see it?
