I was challenged by someone on the forums to top his record of 2000 somthing meters. So I broke it and kept refining my forge island map to where I’ve maxed it out at 4488 meters which equals out to 2.78871 miles. I’ve saved the map and a gametype in my fileshare if anyone else would like to use it to impress their friends by having an awesome custom games kill distance, or possibly refine it and beat my record. You need to use the gauss hog to shoot that far and red spawns at the gauss hog (lower corner of map) and blue spawns at the top opposite corner where he will meet his fate. It takes quite a few shots to get it but eventually you will hit your target.
Good luck and feel free to check my waypoint stats if you have any doubts.
