If you want an extremely easy way to do this with just 2 people set up the match for Deathmatch Fate's Dam. If the person going for the kills stands right behind the grenade launcher spawn point and looks through the nearby door there is a corner where the other person should stand (the corner is one of the few spawn points on the map)...The grenades shot in the corner will keep killing the other player who will continuously spawn and keep dying...If you set the score limit to 20 you can easily finish a game in less than a minute which will also help towards your 1000 match wins.

Note: If done correctly you can also get your double,triple,and quadruple kill with just 2 people

This is basically a video of PSYKOFLOW's guide. Follow his guide in how to set this up. I take no credit for the guide. This is purely idle boosting!

Hey Everyone,

This is my first guide but while grinding this achievement out, I discovered what I believe is the most efficient way to grind wins and kills which can be easily done double boxing.

On your main account, Host a custom player match

Select deathmatch

Select Map
Fate's Dam

Select Advanced Settings which should be set to the following:
Time limit 5
Score limit 20
Auto Map Cycle No

Select Create Game

Have your double box click quick player match which should automatically join your main accounts game.

Ready up both accounts

When the countdown ends, use your main account to go right grabbing the machine gun and left to find the damage power up and then continue down the hall where secondary account is. Do not pick up the shotgun.

Kill it and keep moving around the corner. Take the next right and go outside to find the grenade launcher.

You should now have the damage boost and the grenade launcher paired. You will need to move a little past the grenade launcher so that your secondary account will spawn directly behind you.

Once your secondary account is spawned by clicking right trigger, you will the need to launch grenades from you main account alternating right triggers on both controllers which will should kill your secondary account in one hit each time.

Once out of grenades, use your machine gun and pistol with the same process to finish the match by repeatedly killing your secondary account.

Matches take around 40 to 60 seconds getting 12-14 kills per game. This method will also net you the double ; triple ; quadruple kill achievements.
