A very simple basic mechanic... you see the red lines and the NPC powering up.... both mouse buttons at once.
Am I the only one who is having issue that when you have two, three, or more NPCs stacked up on top of each other... You see those red lines and start interrupting... only to be "interrupting" the wrong one? As simple as this mechanic is, I can clearly see how the system would be unable to tell which one you're trying to interrupt when you have multiples stacked on top of each other. Moving around and trying to get them to split up is about the only thing you can do, but not always an option in small and tight spaces. And in VR, with how hard these things hit, you really don't have a lot of time to be dancing around with 3 NPCs.
Also, I could have sworn that at 1.2 they shrank the hit boxes. At times I see my character going through the motion, yet the interrupt fails. I can only assume it has to do with a smaller hit box... I don't recall having this issue prior to 1.2.
