Re: 360 Acheivement / PS3 Trophy Help and Discussion
The achievement took me around 9 hours to do, doing the brumak mission.
1 - Load up the mission
2 - Shoot rockets at the first 2 groups of locust
3 - Restart
It takes about 20 seconds a time and you'll get 1000 kills every 6-7 minutes.
I was at 16,000 kills when I started at 1pm and finished around 10-11 pm with breaks. It was mind numbing and dull.
