DO NOT USE BLUE GLOW AND NO RECOIL. Even the developers recommend you to turn off the no recoil feature.
Only use ESP but use it carefully, play cautious. Don't track people behind walls. Don't look around the map like a dumbass or they'll notice. Listen to the footsteps, don't preaim/prefire before you hear them. Play legit. If you're high elo it's likely they'll hold really really tight angles so use quick peek as much as you can. Keep your aim at the head level unless you have the info that the enemy is crouching. Lastly, try to understand the depth perception of ESP. Because it's just a 2D Logo, it can fool you.
