attempting to beat my cybergrind PB every day (day 10)[ULTRAKILL]

thing the thumbnail is referencing happens at 15:30 if anyone could explain what on earth happened that would be appreciated. ^_^ I'm trying to add the jumpstart nailgun to the rotation of weapons I use, any tips on how to better use it would be nice. ---------------------- current PB for trying to beat the PB: 80 (45%) achieved on: day 5 0:00 waves 25-29 2:56 waves 30-39 9:42 waves 40-49 17:23 waves 50-59 #ultrakill #ultrakillgameplay
