Blackwind

This is a mildly annoying trophy, especially on the PS4 version where controls don't seem to be as tight. Essentially you need to rack up a melee combo of at least 30 using and melee attacks. The combo counter keeps going up as long as you keep connecting with blows to enemies and don't take too long between landing hits. There is no displayed timer, but it is probably about 5 seconds so it is reasonably generous.

Using your weapon won't break the combo, but it won't add to it either, and Termination moves also don't add (and given the time they take to perform, may end up resetting the combo). Taking damage doesn't reset the combo either, but it can stun you which will eat up time.

In order to reach a count of 30, you will need a fight with enough enemies to keep the combo going, and also need to have them resistant enough that you don't kill them too quickly. I got this quite easily in the Arcadian Research Facility on the PS5, but had to work for it during the Mining Facilities on the PS4.

I would suggest trying to get this out of the way relatively early before you purchase too many upgrades to your melee power, and before you get to stronger enemies in the latter part of the game. For the most part you are likely to be using your weapons as your main offensive strategy, as attacking stronger enemies with melee is going to get you killed. Get this done early and you can approach the game more as a shooter.
