Step 1) Get knife (also recommend getting Big Idol/Run Backwards)
Step 2) Always charge the knife
Step 3) Slide at Suits and just kinda charge at everything else (try zigzagging)
Step 4) Listen to pop-punk (optional)

Other junk
Never look backwards
Spam knife if you ♥♥♥♥ your charge (this is a last resort though cause you can't insta-kill everything in front of you now)
