I beat the game on normal.
I then came back after a month or two in an attempt at a hardcore play-through so I forgot a lot of what I should expect.
I was in Chapter 3 or 4 where you get on the tram.
I was at the part where you fall out and get tangled in the wire. I made quick work of the necromorphs on the ground level.
I forgot entirely about the brute and panicked. I fired at the wire over and over and then the train fell on me.
I forgot you have to actually shoot the brute.
