Reacting to the recent patch that TC has released, I come to offer you a new solution I found to boost your kills. By following my strategy, you will make 85 to 100 kills per round, depending on your own speed performance with the Longshot.
Before continuing, please note that this solution is designed for one player only and requires three controllers.
Set up a Custom, Private Versus match with the following settings :
Map: Asylum
Game Mode: Guardian
Fill with Bots: Off
Rounds to Win: 6 (well, as many as you want)
Respawn Time: 5 (minimum)
Spawn Protection: 0
DBNO time: 1
Weapon Respawns - After Pick Up
Weapon Substitutions: Everything must be changed to Longshot
The game clip is below. Feel free to post comments if you have any question, english is not my native language but I'll do my best to answer you. Also, don't hesitate to let me know what could be improved in this solution.
