Demon Points

Demon Points are a hidden mechanic in Metal Gear Solid V: The Phantom Pain used for determining the player's 'morality.' Demon Points are increased for immoral actions and decreased for moral ones. Demon Points are attained in nearl the oposite ways from Heroism but operate independantly of it. When enough Demon Points are obtained, Venom Snake's horn will grow and eventually he will visually become Demon Snake.

Forms
Obtaining or reducing Demon Points results in Venom Snake taking one of three forms:


 * 1) Normal: This is the default appearance for Snake and can be re-obtained by reducing Demon Points below 40,000.


 * 1) Horned Snake: This form appears after obtaining 20,000 points, the first time. It is distinguished by the metal shard in Venom Snake's head growing significantly to resemble a horn. If the player returns to 'Normal' form after becoming Horned Snake, the player will return to Horned Snake after 40,000 Demon Points from then on.


 * 1) Demon Snake: This form appears after obtaining 50,000 points, the first time. It is distinguished by the metal shard in Venom Snake's head growing significantly longer then even Horned Snake and by Snake becomming perminantly covered in blood. If the player returns to 'Normal' form after becoming Horned Snake, the player will return to Horned Snake after 80,000 Demon Points from then on.

Mechanics
Demon Points can be obtained and removed in a variety of ways. Unlike Heroism, no Demon Points are awarded or removed for completion of objectives.
