I havent tested this out properly, but I am throwing it out there for others who want in on it. I do not know how new it is either.
Climbing up a Ladder, it is possible to shoot at the person waiting for you on top.
You can do this halfway on the ladder looking up, or at the top of the ladder just about when you will climb fully onboard. To do this, always be aiming at where you think you will see someone, maybe it is also better to climb the ladder a bit slower in anticipation for someone.
And here are the button combinations in order to shoot while on ladder. You must be very quick with the inputs.
Controller
- B (Cancel Ladder)
- Hold backwards
- RT (Shoot)
- X (Grab ladder)
Keyboard
- F (Cancel Ladder)
- Hold backwards
- M1 (Shoot)
- F (Grab Ladder)
It is simple, but requires a bit of practice.
You want to Cancel Ladder and Shoot aprox at the same time. I find it easier on a controller as I can just piano the B button and RT.
You hold Backwards because if you hold forward, you may clip your view into the ladder which wont prompt the ability to grab the ladder again.
So, you look up and gradually look forward as you are climbing up.
When you see someone, you quickly Cancel to get off the ladder.
Push yourself away from ladder
Shoot the sucker (And knock him away with the blunderbuss)
Grab the ladder again and hopefully climb up.
In a very quick succession.
This also works with pistol, but it has no knockback, but does 50 damage.
The blunderbuss for the most part is wanted here for the knock back, but there could be a situation where you are close enough to even kill the defender.
Note 1: Ive been succesful enough with only hip fire blunderbuss, aiming down may take up too much time.
Note 2: Galleon ladders seem to shift the camera a bit up when you cancel out of the ladder. Aim a bit lower when it comes to galleons.
