The destroyed extracting system (probably extracting system 3) was a building in the Tundra Sector. The reason for its destruction is unknown, however, it looks like inside was a big explosion which caused a fire that burnt all trees in its vicinity.
There also is a destroyed manufacturing plant in the same sector.
Trivia[]
- This building might be the only structure in the second game that has no ground support at all. Even destroyed manufacturing plant of the Tundra Sector got it for some unknown reason.
