Valkyria Chronicles 4 is a strategy game in the style of the first three games in the series. It introduces a new soldier class known as the Grenadier, who can fire mortar rounds at enemies. If allied soldiers are present to provide battlefield information, they can fire without being seen by hostile forces. When a soldier in your army is on the verge of death, there is a fixed chance that a new system called "Brave" will be activated. When used, players can choose to either restore one Command Point (CP) and increase the ability of a nearby ally, counter the enemy's attack (if downed on enemy's turn) or restore Action Points (AP) to the unit and enable it to move and attack once in an invincible state (if downed on player's turn).
