Objective: Elimination
Recommended Echelon(s): AR/SMG

With one echelon, there isn't a particularly nice way to clear this map. But at least it's pretty easy. There's a fair few amount of enemies around and only a few Heliports to resupply from. This means you'll need to return to the open Heliport right after the one-way to resupply before finishing off the rest of the map.

So, with that in mind, your goal is to secure that one Heliport, then clear the map.

The exact pathing may change due to enemy movement, you it boils down to: get open Heliport, resupply, kill the Golyat on the far left side, return to the Heliport while clearing any Nightmares on the way back, then mop up the last few enemies.
