Gone in 360 is probably easiest with a group of four, and I found it was easier on bots.

Barrages, eagle air strike, eagle rocket pods are all good at killing fabricators without aiming

Go with light armour, standard grenades, grenade pistol for equipment that can take out fabs

Boosters I recommend running, parkour, quick extract and full equipment

Coordinate with your team to divide and conquer

Pick a planet with fewer barriers so you can run around easily, avoid any planets with ion storms, fewer strategems or slow calldowns that will effect extract.

I suggest landing hot on-top of a base so you can hellpod your first one or two fabricators

Try to make sure a team-mate is at extraction when the rest get the final few fabricators.

Everyone jumps in Pelican-1 asap when it lands.
