I know I'm like one year late and I haven't test it again, but I remember weight does matter when it comes to melee attack. It doesn't change the damage but it change if you're going to knock them down or not.

Because what happen is, if you hit someone/get hit my melee attack, the game count it as a crash and would deal stability damage in accordance to your weight class (but the attacker would ignore the stability damage). This is why getting Super Heavy weight class is really important (I think) on melee guy. Just slap lots of heat dispersion so you can always jump.

Also melee doesn't phase through your mech. What normally happens is your attack would knock the enemy down(but didn't kill them), and downed mech are immune to crash so this is why you can "phase through" them. You can test this by getting really light mech, hit them with a sword(weapon that doesn't cause extra stability damage) and crash your mech because you didn't knock them down.

Thank you for this. It's super helpful!

Very helpful, thank you. Also agree that devs need to work on melee.. I think it should show both attack & movement range, shouldn't it?

"Dear Devs, melee needs to show its attack range rather than movement range."
Amen.

Thank you for these video. I did not know dashing negates hitbox. im going to be genji dashing a whole lot more once i practice it.

From what I noticed, the swing always happen at the !!!Middle of the dash!!!. So if you want to check if the swing will connect, plan your attack, hover you mouse over at the (P) in "Melee(P)" text in the timeline, if enemy is slightly to the right( or which ever side you swing from), you'll hit 99% of the time. Also to hit moving targets you can trust the forecast, just adjust your dash until in time (P) your mech is next to the enemy.
Or if you want a easier chances to hit, keep the dash distance to a minimum

Hi, I have tested melee significantly, the red circle indicator is not reliable as to whether someone will be hit..

The melee action takes 1.3s in total.
Between 0-0.5s mark, the mech will prepare it's dash.
From 0.5s-0.75/0.8s the mech will complete it's swing. Any target in the red zone during this time will be hit by the melee weapon.
from the 0.8s-1.3s the mech completes it's backswing animation (nil further damage done).

do you know using melee with ctrl key makes you swing left side? lol it took me way too long to realize that

@Dragon of Fire - "This is due to concussion damage requiring your weapon the be higher level than the opponent."

Does that mean my lvl 5 Vulkan gun with high concussion damage will do NO concussion to a lvl 6 enemy?

From my experiments, thrust functions as a 2nd cap on your melee attack range. The lower value of your max thrust range and your max melee weapon range will your max melee attack range. The range preview will still show you the full attack range, but when you plan it you'll won't be able to go far enough to reach your max range.

Also of note range increases from sensors do impact melee weapons. So both range sensors and boosters help you achieve more ridiculous melee attacks.
