How to Defeat Captain Vor?

Fighting Captain Vor as a boss is simply easy as long as you can avoid taking too much damage and that you have the capacity to deal damage to him. Vor will Have shields which need to be taken down before you can damage his health. Once Vor’s shields are down and you have dealt damage to his health, Vor will either teleport away and use his Sphere Shield ability or use it on the spot.

Sphere Shield creates an impenetrable barrier that protects Vor and other Grineer will be spawned when he uses it. After a certain period of time, the barrier will disappear and Vor’s shields will be replenished, requiring that you repeat the processes of draining them again before being able to deal damage to him.

You will need to repeat this process up to three times in order to kill Vor, ending the mission and providing you with one or two of the main rewards upon extraction.

Captain Vor Info

Captain Vor is one of the most iconic bosses who is encountered during the game. He is responsible for the players’ awakening when on a hunt for Warframes. He is known to be able to understand Orokin technology as his Seer weapon appears to be powered by a Void Key.

Captain Vor Abilities

  • Nervos Mines – Deploys a mine which continuously shocks players within 8 meters for a duration of 8 seconds
  • Teleport – Vor teleports away or heading towards his enemies, positioning him for a better attack or safe retreat.
  • Sphere Shield – Vor creates a barrier around him, preventing any damage and allowing his shields to regenerate.


  • Captain Vor becomes pretty useless when you are using abilities that make you invisible, allowing you to freely deal damage to him and kill him without a single threat to your health.
  • It is possible to get more than one reward when you have defeated Captain Vor and extracted from the mission.
  • Should you be unable to withstand the damage, it’s best to stay away from the fight and try to get shots off at Vor from a distance.
  • When Vor uses his Sphere Shield, try to take out as many Grineer enemies around as possible while he recharges to lessen the enemies you will be fighting.

Final Thoughts

Captain Vor may not be one of the strongest or smartest enemies, but he sure can pack a punch when taken lightly, especially for new players. Try to watch out for his mines as they can deal continuous damage and take note that you can always lure him out of the area to avoid fighting in the wrong area since he will teleport to you from time to time.

The Grineer enemies backing Vor up can be quite a nuisance but keeping a distance from them is not too hard to do. A good technique would be to damage Vor and take the rest out and repeat until he is dead. Captain Vor will have pretty much the same stats and movements in both Tolstoj of Mercury and Extra of Ceres, making this guide suit both instances of the boss.

Defeating Vor won’t only give satisfaction; you get a lot of goodies in return as well depending on which mission you have chosen to partake in.
