What is a hitscan weapon?

a hitscan weapon is one in which the bullets will instantly hit the target as you move your cursor over the target. Ie you can flick your mouse across an enemy and have contact regardless of distance, meaning the bullets travel instantanious

the term is quite popular in Overwatch where most character have travel time for their weapons while only a few have "hitscan" guns ideal for taking out high mobility targets

COD is an example of a game where all weapons are pretty much hitscan because their is no bullet travel time in multiplayer (they tweaked this lsightly for bop4 but for blackout reasons)

in this game, i can forsee it being a gun that will have much faster projectile velocity, making it easier to hit fast moving or far away targets. meaning you wont have to lead your target.
