First clip - I just killed the pyro at cliff before the clip started so I guessed that he would've came back for me cause he had been playing around there most of the game, (idk if this was the point of the clip but) I then did some dmg but he escaped to the big health pack and so I checked the other side but he did not come out, meaning he went back out from where he entered and after headshotting the pyro at the cart, I guessed he would've still be on the cart but he wasn't there so I guessed he went for the pack, after hitting him again, I rotated cause I thought he would've went to the cart but wasn't there so I rotated back to be safe from the pyro I killed and managed to find the other pyro.
Second clip - Easy and common spy check area cause it pretty much acts as a hallway/corridor up the tower but still got juked anyways
Third clip - Common spot to find enemy snipers (been killing some sniper with a elongated torso from the store -_-) or just anyone that exits from the top spawn tbh, the spot where I aimed at totally coincidental, it's just me hiding my dot from anyone that wants to peek, if it's about the engie then i'm just checking my surroundings for players
FREAKIN HAZE
Fourth clip - I either saw the trail, and/or most of the game when I spawn I always prezoom the tower to look for people that just sit there and then I just followed him - guessing he would have went for healthpack after dropping down (I didn't know he was low and thought he would've climbed tower from the other side again), then saw him run towards their side but didn't see him after peeking the corner so he could've only went up the tower since he just got health~ tyvm!
