Grade chips. (Terminator: Resistance)

A question of this kind....grade chips in Thermals pure random or it depends on you that bucket killed?

Why do you ask.
On the EXTREME level if you fired upon the enemy in Louth will be broken chip that a gun turns into a Shopping resource.

If killed vanshotom Crete - chip was of better quality and the option.
And here I was fucked up.

It turns out that the best way to get the chip upgrade to kill the enemy with the least damage thereof.

Tried to protest - mowed 800K pure electric knives, but especially to the difference between this method and blow them up on banners and S4 I have not noticed.

But a couple of times noticed a purple chip fall when Negril crowd of thermals around the the canister and detonated it vanshotom. Somehow from the explosion of canisters they suffer less and of the type that swept them from it is better than disperse them from stretching or C4 at his feet.

The same goes for the Grenade canisters.

Watched a lot of passes and some drifters 4-5 mission already had full sets of purple mods. While playing as fierce Nubia.

How to produce chips of high grade and with maximum settings if they are not random?
Nowhere nafig there is no disk imaging in this regard.
