Holy moly I just reached mission 6 on this, and it is incredible.
At first I thought it was fun but I wasn't blown away; I was mostly playing conservatively and getting the hang of it.
Then, tonight, it clicked. I got into the rhythm of dashing around, quick-swapping weapons, juggling multiple opponents at once in a frenzy of pyrotechnics, and it was f---ing amazing, some of the most fun I've had with a game in a long time.
After clearing a particular room I felt like I had to pause and physically catch my breath from the intensity of it.
Great game.
