Thank you for playing!
😱 I never knew that's what they were for but that's amazing, thank you for letting me know!! Originally I had it calibrated so anyone at the front of the map would be hit with bullet drop enabled with the center of the crosshair, then the next level would hit enemies in the middle, and the last level would hit enemies at the back, however I decided to introduce zooming in and out very late on and without some kind of zeroing system like you get on Sniper Elite it made those notches rather useless!! If I ever revisit this style of game or even another shooter in the future with a sniper, those notches will be given more thought and practicality!
