Most likely a strat ima start doing as it only 1:45 ish into the run. I was toying around with the bottle glitch (also learned that with the bottle, boundary breaks seem 100% easier to do with bottles). You can get pretty crazy launches with bottles and railing. I've also seen you can glide quicker than what the speed is in the video.
There is a few ways this could be useful, will be posting them when I find a way this could be useful. You can pretty much go through anything as long as there isn't a invisible wall between you and the wall. Tried in the tutorial but you need to do all the objects and the game will bug out during "Clear the area around the vehicle" if you just skip pass everything.
You just need to get grabbed by a zombie and as soon as you break out of his grab, spam the roll button.
You can also boundary break with bottles but im 99% sure it only works on gates and railings and its also semi difficult to do.
You can pretty much just skip over the puzzle part and grab the axe through the wall. I tried to boundary break through the wall/fence but just couldn't get it, maybe someone else can though.
With doing this skip you can save 3-4 mins depending on how your RNG is.
I plan on speedrunning this game at some point but knowing it's a gamemill game I decided to look for more skips/random ass glitches or maybe something that could be faster.
During Seed when you're tasked to shoot all the alarms, you can clip out the first gate near one of the first alarms you shoot. When you clip out there is a invisible wall but maybe there is a way to clip through the invisible wall? There is part that slightly levitates you up but for some reason you're constantly getting pushed to the left. I learned that you can easily clip back in bounds by getting grabbed and rolling after you get grabbed.
Next is probably more so a question rather than a skip but why don't you just snipe this alarm? It's a tough shot but isn't impossible to hit.
