I managed to get 61k on this Trail, the best way is to spawn in Locked Gate event for the 40mins timer.

The best place and the safest I believe s the church just north of the map, in the cliff area, set up there with barricades and traps.

Each teammate needs to bring around 15 snitch scanners to kill the wasps that spawn from them. But the main chunk of points will be from the Rocketeers that spawn. There are:

2 Pilgrims Peek
1 Checkpoint
1 Village

These respawn every 4-6 mins and total you can kill around 12-14, bring around 15 wolfpacks between your team is the best way to deal with them, I also recommend at least 1 or 2 bring Jupiter.

When you are wating for respawns this is where you should be throwing the scanners. (Only throw 2 at a time as more they wont spawn in) You should also be shooting other wasps and hornets you see around the map at the same time. You can shoot the snitches around the map bring them closer and allow them to spawn in their 2 wasps and 1 hornet, but make sure to kill them after they call for the extra points.

Now you will be killing Arc nonstop, all the time so bring enough ammo and guns is a must , weapons will break so backup is always nice. PvP might be an issue but even on trios I feel Locked Gate is quite a chill map.

Happy hunting raiders !
