I kinda get it I kinda don't. my aim button is ctrl and my fire button is spacebar. can someone explain to me with those buttons how I would quick shot.

1: Press AIM. 2: While hold AIM press SHOOT. 3: Release AIM quickly and keep holding SHOOT. 4: Mash AIM fast while holding SHOOT.

Try first with the shotgun or grenade launcher, since the windown for quickshotting is bigger.

can take a while to get used to the biting point of quick shooting, what i do is hold down the fire button and mash the aim button in a specific speed (which you'll get used to very quickly), any faster, and the quickshot won't work.

To be fair, you dont need to mash, you just need to press the aim button in a specific frame while you are still holding the shoot button, but you have like a low Numbers of frames (idk how much it is, maybe 2~5, which is less than 0.2 seconds), because of that it is easy to just mash the aim button.

There are different techniques, but this comes with experience. Wusscake, for example, does a triple tapping to quickshotting with the GL in RE3 and a precise single tap for handgun. For Magnum in RE2, i like to wait Leon start to drop the magnum after the shoot animation before starting to mash.

These guys explained it well enough, but i will say @Bigaloe forget quickshots for now and focus on the route and menues, all of the bosses can be killed without quickshots and without any major differences in the fights.

I learned this skill from certain Youtuber, but I still hard to use it. It works from time to time, it's not stable for me.
