In Death Room, 2 v 4. I had a trainee on my team, and had 4 enemies (In a clan with high Kdr). I saw my teammate shooting so i took my nade and was about to throw.. but remembered that FF was on. So I threw it to my foot and ran forward.. 4 kills with the nade. Turns out Trainee was shooting at a random wall, 4 guys were chasing me with a knife. All 4 of them called me hacker for thinking that they were chasing me and I somehow calculated to kill all 4 w/o looking.
