This guide aims to help you snipe the Teklords from far away. There is a map image and an aim image for all Teklords, except Dallas Dimarco, as you can't snipe him. ALL of these require you to be in the corner so that it is consistent. Note that it can be tough to get into the corner at Marty as that's not a 90 degree corner. Try aiming a bit to the left when running into the wall, but not too much.
Sonny Hokouri: Note that the texture looks different if the door next to it is opened. Because the door can open if you get too close to it, it might be better to learn the amount of lines from the corner to the spot instead.
Miles Connor: This is almost the same as before but you can use this small invisible corner right at the beginning instead of going to the big corner Note that it might be better to aim to the right corner of the dark pixel instead of the left.
