In this example, I'm fighting 16 Experienced Bots. No Powerups (Deemer or Amp).

While working on my aim I became curious to see if I could break 1 Minute for 25 frags. Unfortunately, after many attempts, 1:13 is my best time.
I also tried camping but it wasn't as fast as Run N Gun.

You need a good spawn (not dying when you spawn and close to a sniper) and some luck with the bot's locations so you don't waste time looking for them.

Give it a try and post your time!
