A sidestep (or "strafe") in first-person shooters is a quick lateral movement—left or right—used to dodge incoming fire while keeping your crosshair on target.
In fast-paced shooters (Valorant, Apex, Overwatch 2, Call of Duty), players who master sidestepping survive significantly longer and win more aim duels. It's a foundational mechanical skill, on par with aim and map knowledge.
Core Principle: Move laterally to evade, not away.
