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 (Hive Lord bones?)
Visually-
Winding trench, lots of bones in the interior and exterior
On the Map-
S-shaped trench, bridge across trench visible in interior
Hole count: 10
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 a walking barrage in addition to 380. I attack one of the walled in portions with an elite bug hole via 380, then I run through the nests eruptoring a few holes exposed to the perimeter. I toss a 500 over the bridge to take out a hole on the other side, then I eruptor an elite and a normal bug hole on the other end of the base. I destroy the last hole with 500kg.
