Can someone please tell me how & which buttons do you use for the skill checks on Xbox before I ?

It should tell you when the skill check comes up in the middle of the circle.

Left bumper is default skill check for Xbox. The small button on top of the controller but closest to you (make sure you’re not hitting Left trigger by accident).

If you’re having any trouble with skill check timing then depending on your monitor/tv make sure you set the screen setting mode to “game”. You’ll see other options like dynamic, movie etc but especially on a TV, setting it to “game” will eliminate a delayed input and instead the skill check will feel more synced with what you see on the screen and when you actually hit the button. This is equivalent to disabling “VSYNC” on PC if input delay/laggy skill checks is ever an issue. Also remove digital noise etc

I highly recommend remapping your controls slightly or at least try it out as well. My number 1 tip is to remap interaction such as vaulting, dropping pallets, entering lockers etc. The default for Xbox is Right bumper but RB is also the same as healing someone for example. You can leave basic interactions like unhooking and healing bound to RB but if you bind the other interaction to “A” on an Xbox controller you can run up to heal a downed survivor at a pallet without the risk of dropping the pallet instead of healing or you can get a vault instead of healing a downed survivor by the window overriding what you intended to do.

Hopefully that helps and makes sense.

same thing for PlayStation.. make Vaults X for example and change active ability to something like Square. You can bind ability to R1 so you can freely move your camera and not have to let for of the joystick for dead hard.. that one takes getting used to because you’ll have to come to a full stop before an unhook for example otherwise if you’re injured you’ll dead hard in their face for no reason or while running over to co-op a gen… true story.. I dead harded to a gen by accident once and a random Dwight flat out DC’d🤣

If you go into your controller settings you can see what buttons you currently have set for Interactions, Actions, Skill Check, and Active Ability. The game always has a prompt pop up anytime you would use any of these. The button you set for skill checks if it's LB will always be LB unless you change it.

Interactions are cleansing totems, generators (not the skill check, just working on generator), healing (again not the skill check just healing), opening exit gates, unhooking and hopping into the hatch.

Actions are vaulting, dropping a pallet, hopping in/out of locker. - I highly recommend setting this to a different button than interactions because this can screw you up later on like if you try to heal someone by a pallet and you drop the pallet instead.

Skill check is your skill checks while working on generators, healing, hook/cage struggle.

Ability is using ability associated with a perk like Dead Hard or For The People.

Definitely do some bot rounds in the tutorials because it will help you out a ton in getting used to the controls and also if you change buttons seeing which ones feel best for you without being in actual match. If you have friends you are playing with you can also do Kill Your Friends matches to have an even more casual time feeling out the controls.
