Easier mega nest variant, but not as easy as Crater.
This mega nest has a winding trench with bug holes dotting the edges, with two walled in portions at either end to guard 2 elite bug holes.
Has lots of large bones sticking out of the ground in the interior and exterior portions.
Visually: Winding trench, lots of bones in the interior and exterior.
On the Map: S-shaped trench, bridge across trench visible in interior.
Elite bug holes look like the holes found in Stalker Lairs and spawn either Alpha Commanders or Bile Spewers on Bile Spewer constellation maps.
The holes are close enough together in this outpost to not require an Orbital Walking Barrage in addition to an Orbital 380mm HE Barrage.
I attack one of the walled in portions with an elite bug hole with the Orbital 380mm HE Barrage, then I run through the nests and use the Eruptor a few holes exposed to the perimeter.
I toss an Eagle 500kg Bomb over the bridge to take out a hole on the other side, then I use the Eruptor to close an elite and a normal bug hole on the other end of the base.
I destroy the last hole with another Eagle 500kg Bomb.
