It's funny - I didn't even finish in the top half of this Widowmaker-only headshot-only FFA deathmatch custom game, but I was still really happy with it. I had a decent k/d ratio (compare against others in the same game), and felt like I was in a really good rhythm, particularly in the second half. Plus I just quite liked several of those shots. They felt right.
Bang. Bang. Bang. ♥
