Shadow Claws

Shadow Claws is a ability for Alucard to use to climb up highlighted walls and slowly decend walls down avoiding any damage. He obtains this after sucking the Reaver's blood eventually spreading through Alucard's veins growing dark claws on his fingertips. later the ability is used by Trevor except he uses his combat cross to mimic the same ability with the stake part of the weapon to jab through a hole in the wall enough to support Trevor then jump and the sharp point of it to decend down walls.
