Brok's bottom-feeding strategy. This carries no risk, there's no quickplay numpties to screw it up but its pretty dull and won't net any rarer materials but still good for filling in a level or where you don't have long to play (or matchmaking is down...again)
Planet - Hellmire - this is the best option due to the smallest travel distance but any bug planet will work
Difficulty - Trivial
Mission - Eliminate Brood Commander
Weapons selection is irrelevant
Strategems - Not really important but I use Orbital Laser, Eagle Airstrike, Guard Dog Rover and Gatling sentry. You just need something you can fire and forget into the boss area and Guard Dog is useful since it basically solos all the trash at this level.
Drop into the mission between the brood commander and the extraction point. On Hellmire it is possible to actually complete this mission from the extraction point itself depending on the exact layout of the tiles.
Call in Guard Dog
Call in Laser and Eagle on the brood commanders lair whilst waiting for guard dog to land. Its always identifiable by red coloured rocks surrounded by the yellow mine things. Aim for the central area of the red rocks.
No need to wait around, run to the extraction point whilst your strategem(s) kill the commander and call in shuttle.
Total time in mission from extraction to extraction (including all load screens) is around 6.5 minutes. Exp 210 per mission. Total exp per hour - 2000
If the mission doesn't spawn on a planet, just move to another one.
Yes, it does feel a little like killing boars in the forest
