The Demon Points system tracks your actions and influences Venom Snake's appearance. Killing enemies, developing nuclear weapons, and failing to extract allies will increase your Demon Points, causing Snake's horn to grow and making him appear bloodier. Conversely, rescuing prisoners, extracting animals, and disarming nuclear weapons will reduce your Demon Points. While it doesn't directly impact gameplay, it's an interesting moral reflection of your choices. Aim for a 'Hero' appearance by minimizing lethal actions.
