takes place on the floating island of Endia, which is sort of the end-hub for all of the other universes. After exploring a bright light in a cave, a young boy named Hyouma falls into the world and is reluctantly pulled into a war. During his travels, Hyouma learns that he isn't the only traveler to find Endia and meets a number of other characters from a variety of other games, including Shadow Hearts
, Blazing Souls
. The convergence and interaction of characters from several different games is the game's most interesting aspect, though only if you know who the characters are - otherwise they'll just seem like little more than stock characters since they game really doesn't take much time to explain who these people are.
Most of the game's plot revolves around finding keys that will help you unlock gates, which lead you to new characters and locations. If you decide that you need some extra experience or rewards, you can also take part in a series of side-quests, though these never go any deeper than giving you one extra battle to take part in - so you won't miss much if you decide to skip them. This is actually one of the game's weaker overall aspects; there isn't much else to do other than fight. There's an item synthesis system, though it doesn't add much to the game. Also, given the unique leveling system, there isn't a whole lot in the way of stat management.
Gameplay is largely tactical and resembles something along the lines of Phantom Brave. Chaos Wars ditches grid-based movement in favor of a more free-form movement. During their move phase, a circle appears around a character, denoting how far they can move. Rather than having the option to use a skill after moving, everything a character does uses up energy, so even if a character is within spitting distance of another, he can't use a skill if he doesn't have enough energy. Energy slowly refills over time, though most of the game's strategic element is built on getting the most out of a character's energy reserves each turn.
