I just learned about a driller trick. I saw another player dig a tunnel up above the caretaker and drop a c4 on its head at the start of each phase. 2 c4s shut down all the vents in a few seconds. I tried it myself and it totally feels like cheating. You can basically skip half the fight this way. 1 supply pod right next to you in the ceiling means you can skip all vent phases
I’ve been doing this since the fight came out, it’s a fantastic way to make a really long fight into something much quicker
