Same, it's pretty hard to do tank run on your own especially on tight maps like dead center Try playing with others, and if a tank appears in front of you just back up to the previous area while shooting it or something
Lmao its not a mod try playing tank run and youll know, anyways because pipe bomb is useless at the tank run (because theres no normal zombies)valve makes the time on the pipe bomb shorter so the bomb will explode right away when you threw it
