The Catapult Crash Technique was a move that was created and mastered by Sir Galleth Cooper. It is featured in Sly Cooper: Thieves in Time. This is one of the techniques that Sir Galleth did not put in the Thievius Raccoonus or the Cooper Vault.
The Catapult Crash Technique is a powerful charge that breaks through objects while jumping from a wallhook. It also is notable for going higher than Sly Cooper's regular wall hook launch. The move is performed while on a hook as Sir Galleth by holding then pressing to launch.
