CTRDDA (or Chase The Rocket Don't Do Anything) is a special type of DDA which involves the ninja to follow the rocket, instead of the other way around. These are very difficult to make, becuase the involve the ninja to be within a frames of the rocket. The first CTR was made by Romaniac, who was inspired by Clifty's The Chaser's War, even though Clifty's wasn't really a CTRDDA. Since then, Romaniac has posted #2 and #3. A CTRDDA usually has alot of close calls because it almost always hits the rockets flaming.
