I love killing people with Frag grenades. I don’t know why it probably started when I was playing Rainbow Six (the original), and would bounce them off doorways, lob them around buildings, and see my kill pop-up. Using frags is another element of fps that I enjoy besides the usual running and gunning.
Throwing a cooked frag takes a bit of practice to get it right. First you have to hold it for a few seconds, but not too long or you’ll die. Then you need to aim it by tilting your view upward if you are trying to throw it over something or just straight ahead if you want to bounce it off a surface. It can take some practice getting used to throwing grenades. I know it took me some time before I felt comfortable using them.
I made a video, a compilation of some of my favorite frag kills.
