Chrono Chaos, also known as Chrono Dimensions, is the third game in the Chrono series, not counting Radical Dreamers. It takes place in a parallel universe to the standard Chrono world, but has many tie-ins to Chrono Trigger. It brings back the time-travelling element from CT. It is for DS and uses CT's sprite style and gameplay style. There are also some anime cutscenes. The game's tagline is "Don't like history? Then change it."
