Teenage Mutant Ninja Turtles: Shredder's Revenge

Certain projectiles in the game can be deflected if you attack them. The main ones are the arrows that the archer foot soldiers shoot at you, but some other can be deflected too. I personally unlocked this naturally during Story Mode without even knowing this was an achievement, nor trying to deflect projectiles at all, but in the middle stages there are often archer enemies that show up on the sides of the screen. Attack their arrows to deflect them, and after doing ten cumulatively across both game modes and all replays, this will unlock.
