So I looked through the forums and guides but didn't see anything on how G1 is defeated with the knife only on PC 120FPS. It's pretty self explainatory but I would like to hear from some of the PC runners. Where is it you are are aiming when knifing G1 and why? I'm guessing it's to hit him at most 3 times but want to be sure. I'd like to try it on console but need to know how and why it's done this way.

On Leon, run up, aim down, as down as he will go, and have birkin on leon's top right. Make sure the swing is connecting on birkin small arm, in addition to hitting his 2 legs. After 7 swings, he'll start to spin, aim up, and swing once, no more it's very important, then go back to aiming down, and keep swinging. While Birkin is leaning down and transforming get his big arm at the start of the swing animation in addition to the regular hits. If you get 2 hits on the big arm then there's a possibility you'll get 17 hits, but you can go as high as 20 slashes before he grabs you, so it's pretty safe.

On Claire, same thing, but have Birkin even more to the right because Claire has a much better swinging animation, she's capable of cutting Birkin's entire body corner to corner. After 8 swings, aim up for 1 swing and aim back down, and it's easier to get the swings to hit his big arm while he's leaning down. Best I've gotten is 15 slashes, but I believe a 14 slash has been done by 7rayD who might be using a different swinging pattern.
