Thank you : ) Actually, way to speedrun it faster than 0:53 exist, but it requires REALLY good skills, which I don't have, but 0:49 I believe is possible.
Route I used may be even better, but it requires less hovering moments (near gun tower) and better knowing of script zones (I thought, going near ruins means activation of script, but I'm wrong). And yeah, it's still better than out-of-map (T-T)
To be honest, some parts of speedrun I did by accident, like that sniped sentry: I tried to do this many times, but yeah, that's HARD move. I spent around 50 attempts at this part, cause I'm weak.
"That flight route after you've got the sentry is also interesting" -> another move I did by accident. I decided to go that way cause my radar was closed by timer (I put it there cause right part of the screen required for me to move faster (I'm moving my mouse diagonally to move faster) so I can't put it there)
" how many attempts that would have taken " -> https://prnt.sc/G7aoEA3ETAXp my folder with records after speedrun
