So I am the Vamp boss stage. And i know that i have to stab him with the syringe but i dont know how to grab him with the CQC. I have read the briefing on the restraining part but it looks a bit confusing with all four parts on the screen at once. I seem to only be able to throw him to the ground. I dont know how to grab him. I have been trying for a few hours i'm starting to get angry now.
