There are 20 targets in the map.
here's a little help on finding them. of course i won't tell you the exact locations. feel free to add to this with exact locations if you find them.

Cars. make sure to check all cars because i have hidden targets in them.
Walls: on walls and barricades are some of the targets.
Graveyard: inside the graveyard there are targets on gravestones / fences.
teleporter. one target is found after teleporting. (make sure to stay on the road because i havent yet fixed the death barrier due to issues with modtools on my end.
jug: at jug theres a target in front of the machine and on the wall.

and for the most difficult one.
In one of the big trees at jug there's a target hidden in the shadow. you can see it easily once you know where it is.

good luck!
