I used to be terrible at First-Person Shooters. I would panic, spray my bullets everywhere, and get taken out instantly. After deciding to actually practice my aim in games like Shell Shockers and Venge.io, I discovered that good aim isn't just a natural talent—it's a learned skill.
Here is exactly how I improved my aim, and how you can too.
1. Lower Your Sensitivity
This is the single most important piece of advice I can give you. When I ask my friends what sensitivity they use, it's almost always way too high. You should be using your entire forearm to aim, not just your wrist.
Lowering your sensitivity (also known as EDPI) gives you vastly more control over micro-adjustments. It will feel sluggish at first, but stick with it for a week, and your accuracy will double.
2. Crosshair Placement
Stop looking at the floor! When moving around a map, your crosshair should always be at head-height (or egg-height, in the case of Shell Shockers) and resting on the exact spot where an enemy is most likely to appear (like the edge of a doorway).
If your crosshair is already where the enemy is going to be, you don't even need to aim; you just need to click.
3. Tracking vs. Flicking
Tracking is keeping your crosshair smoothly on a moving target. Flicking is rapidly snapping to a target that surprised you. Practice tracking first. A smooth tracking motion with an SMG will consistently win fights against someone trying to hit crazy flick shots with a sniper rifle.
