Recoil Lab
Shoot a weapon off the wall rack to hold it, then work its spray on the wall panel: every automatic weapon has a fixed CS2-style pattern that kicks your bullets up and sideways. Pull your mouse the opposite way so the whole spray stacks on one point. Turn around to transfer it onto the bot line. Everything is in the world — no menus.
Turn on the ghost pattern: those dots are exactly where your bullets go with ZERO compensation. Your job is to trace the mirror image with your mouse. Learn the shape, fast at the start where the climb is steep, then ease off. Five focused minutes per weapon beats thirty on one.
