and begins at "Deadly" (D); progresses through "Carnage" (C), "Brutal" (B), and "Atomic" (A); then, advances through one last bar of grades containing the phrases "Smokin'" (S), "Smokin' Style" (SS), and lastly "Smokin' Sick Style" (SSS). Stylish combat is the focus of the game, conveyed through unbroken combos of varied attacks while avoiding damage. The player must avoid enemy attacks to continue performing combos, often by memorizing attack patterns. The Devil Trigger is a super state that enables the player to become more powerful adding a slow but steady health regeneration, with increased damage done. Devil Trigger can be activated by pressing the button to trigger it when the gauge is filled. Some changes introduced in Devil May Cry 4 are the presence of two playable characters, Dante and Nero, and a slight modification to the shop system. A new currency, Proud Souls, is used to buy new abilities while Red Orbs are used to buy items. Proud Souls are rewarded at the end of missions; the amount varies depending on how well the player performed. The cost of abilities increases with the purchase of other abilities, though all abilities can be sold back for their original price. The player plays as Nero throughout most of the game. He is equipped with the Red Queen sword, Blue Rose revolver, and the powers of his Devil Bringer. The Red Queen features an Exceed Gauge that can be charged up to the 3 stages, allowing for subsequent attacks that are more powerful than regular slashes, until the gauge empties. Nero also has the powers of his Devil Bringer and can use it to pull himself towards enemies or vice versa. The Devil Bringer may also be used for context-sensitive throw attacks, leading to high damage and various effects depending on the enemy. Nero's Devil Bringer also gains new abilities during the game, including being able to detect secret missions or caches of Red Orbs. Nero eventually gains the ability to use Devil Trigger after getting the katana known as Yamato. This increases his Devil Bringer's power changing its attacks into more powerful versions with different animations. The player plays as Dante through seven missions, taking over halfway through the game. His gameplay is like that in Devil May Cry 3. He has access to multiple melee and ranged weapons which he gains after boss battles. He is able to cycle through them
