The "Fluke Frag" with a small amount of planning, experience and anticipation turn it into a "leet frag" (or however you kids are calling it thesedays lol)
But the feeling of escaping the 'big one' is a nice feeling. You'll find in CSS, people will just rush in if you wait 10 seconds and position yourself well. The scout is your best friend here, quicker reload makes for better mistake recovery and headshots still kill.
I remember the end of ShoC, I had at least 15 Monolithians pinning me down. Knowing that only headshots work, I used grenades to close the gaps between them and I. Eventually I was close enough to use the hunting rifle, a quick double pump from 20ft made them dead as a doorknob. Then a few glitched and sat down, god bless buggy ShoC Vanilla, LOL!
Plus Grover, Auto-Shotties? C'mon, ya noob! lol. Use the M3!!
