So you've fixed the vehicles, but the the nova knifes haven't gone through much change. Equipping the nova knifes is suicide for the most part, The description for a nova knife is, "A close-quarters melee weapon, the nova knife is as deadly as deadly a weapon as anything on the battlefield. Its name derives from the heated plasma edge of the blade - formed by a thermic igniter and linear gravity condenser - that, in skilled hand, can be used to carve through even thickest dropsuit armor." So being a close combat weapon, it should specialize more than any other weapon in attack speed and maneuverability at that range. If a knifer is behind the enemy, give the knifer some bonus (remember that any mercenary at any distance can easily take the knifer out). Knifing an enemy in the head should also do bonus damage. I've noticed that the knifer isn't very fast, I was expecting a significant speed boost since it's lightweight, and the speed boost is necessary because there are enemies that walk faster backwards than a knifer walking towards them with a charged knife, resulting in death. please fix the knifes, i really want to specialize in them, but all the disadvantages are far greater than the fun in being a silent mercenary.

On a SLIGHT mod to that: you could make it so that if a charged blade "touches" the enemy's actual dropsuit, they die. But that does mean they have to make it through the shields first.

So, normal effectiveness against shields, but 1000% efficiency against armor?
