Warframe 1999 has added two new Exterminate Missions that take place in Hollvania, which will have either the Scaldra or Techrot occupying the area.
You will need to fight your way through these missions to kill a large number of enemies, which will be your main objective.
During these Exterminate Missions, you are likely to encounter a Scaldra Supply Cache, which will yield additional rewards if you successfully open them.
Hollvania Exterminate Mechanics
Upon starting the mission, you will begin heading to certain locations on the map where your enemies have spawned.
As you continue to defeat enemies, more will spawn, and their numbers will soon increase to the point where they may close in on wherever you are.
Your goal is to kill the specified number of enemies and once you have met the target amount, you may head to the extraction point.

Verdict
Enemies that you encounter in the Hollvania Exterminate Missions will often have a higher level than most of the enemies that you encounter in missions outside of Warframe 1999.
Depending on what you have available, the use of powerful modded Warframes and weapons will determine how quickly you can clear out the areas of each mission.
During the missions, enemies will begin to spawn more often after opening a Scaldra Supply Cache, making this necessary to speed up your progress.
