Constantly using C. Tank at the start allows the One Horns to sync up, then A. Bahamut can nearly kill them all in a cluster, or sometimes it can kill them all at once depending on how close the One Horns are. After that Maglev has to be timed very well to hit the Bear. There is two other ways of doing the level, one involving a high leveled C. Titan shockwave Cat Cannon, and a cheese Knockback method.
