Description (written by the developer; not a statement by this register)
Immune System Fighting Simulator is a game that aims to simulate the inner-workings of a human body realistically. It uses proper scientific research and data to induce an authentic experience for players. Although Immune System Fighting Simulator strives to provide accurate knowledge, some gameplay mechanics may sacrifice specific details. New users should read the tutorial before playing the game to understand the overall structure better. The revamp update (part 1) is out now! IMPORTANT NOTES: Certain resolutions may have trouble rendering GUIs. Please submit a bug report if your device has any issues. If you had trouble purchasing a gamepass, please contact a moderator.
