Invasion Mission Enemies Don't Spawn Until Near The End

[TriangleMann]

Specifically for siding with the Corpus, Grineer enemies won't spawn until the last few rooms, and then you have to backtrack back and forth through the rooms for them all to spawn.

 

EDIT: To clarify, it's the "Invasion: Corpus" when you are starting in a Corpus ship, move outside of the ship, and take a teleport gate into the Grineer ship. All the Grineer seem to be replaced by friendly Corpus until the last few rooms where all the Grineer are clumped up together, so one would be running alongside a massive Corpus army.
