As some of you know, the reload-canceling technique(Shoot-Shield-Switch) has apparently one way to work well, but i think there's a couple more ways that could work as well.
Default:
Shoot- RMB (LMB)
Shield- LMB (RMB)
Move- WASD (IJKL)
Weapon switch- Spacebar
But how do you switch between two weapons when you've got 3 or 4?
Try this:
Weapon 1: Scroll up
Weapon 2: Scroll down
Weapon 3: Q
Weapon 4: Spacebar
Shield: Ctrl
It's a bit manual, but can work from my experience. Here's another one for those with different finger movements.
It's slightly more difficult:
Weapon 1: E
Weapon 2: R
Weapon 3: Q
Weapon 4: Spacebar
You can also switch 3 and 4 with 1 and 2 if you prefer the lesser reach.
I've also become adapted to something a bit bad and good. I wouldn't recommend it, because after getting used to it, it's harder to use different styles. But a few pros are it's rapid fire if coupled with medium/high ASI, high DPS with alchs, and massive damage on single targets.
Meant for only 2 guns:
Weapon switch (next): Spacebar/Scroll up AND down
If I could get a few opinions on this or other methods, that would be great. I appreciate any thoughts/criticism.
You know, if you learn to double-switch and use a next/prev setup, you can just use whatever weapon you'd like to your heart's content.
A lot of people seem to like alternating weapons for some reason. :`
For the curious, my control scheme is this:
WASD - Movement
LClick - Attack
LShift- Shield
Scroll - Switch
People ask me about it often, but honestly, use whatever feels comfortable to you.
