Immune Simulator

About

Immune Simulator lets you play as a survivor who finds an ancient computer capable of altering history between humans and zombies. You view records of past conflicts and tweak the data to change outcomes, but these edits shift the balance of power in your own reality. The twist arrives quickly when your companions start mutating into something else as you manipulate the timeline. This hybrid title blends strategy planning with narrative choices typical of visual novels, requiring you to manage resources while navigating a story where every decision has immediate, often dangerous consequences. The core tension comes from wondering if the machine is salvation or a trap for everyone involved. Community ratings suggest players enjoy the unpredictable way changing past events spirals into strange new scenarios. You might save your team in one playthrough only to face a worse fate in another because of how the simulation reacts. The game avoids simple good or bad endings by making every alteration feel personal and risky. It stands out for its direct approach to storytelling without relying on complex mechanics or open world exploration.

Storyline

The story describes a world in which humans are fighting against zombies and losing. The female protagonist accidentally finds an old computer with software that records the process of human-zombie conflicts, much like historical documents. The protagonist attempts to operate the computer and view these historical records but discovers that the historical data can be changed. After leaving the machine, the balance of power between humans and zombies in the real world also changes. Just as she thinks she can use this machine to turn the tide against the zombies, her companions begin to change one by one. Is this machine a salvation from God or a trap from the devil? What secrets are hidden in this machine? It's up to the player to discover.
