Rainbow Six Extraction: Where to Find Sludge

gamerant.com:

Rainbow Six Extraction players will want to avoid Sludge as much as possible when completing main objectives on all map types. There are certain research challenges that require the spitting enemy to be found, however. The Caustic Buddy research assignment is the first Sludge challenge many players will come across, but starting it actually triggers a bug that reduces Sludge spawns to nearly non-existent.

Thankfully, there is a workaround for the annoying glitch. Players can use this guide to help them find Sludge enemies in Rainbow Six Extraction, and learn how to kill them without the enemy multiplying to clear all the Caustic Buddy research challenges in San Francisco.

Rainbow Six Extraction: How To Get XP Fast

As the Caustic Buddy research bug limits the spawn rate of the slimy enemy, the difficulty needs to be raised to at least Cautious to find Sludge in Rainbow Six Extraction—although Critical difficulty is recommended. This has a higher chance to activate the Spontaneous Sludge mutation that turns enemy bodies to Sludge when killed.

After the difficulty has been changed, go to the Enterprise Space Foundation or The Tenderloin Neighbourhood areas in San Francisco and start killing enemies in the hopes they turn to Sludge. There is still a chance the enemy will spawn in the wild, however, so keep an eye on the ceiling and walls for an orange, circular slime. Using scanning items equipped by some operators in Rainbow Six Extraction can help identify Sludge quicker. Keep using this method to complete the Caustic Buddy research challenges.

Once a Sludge has been found, it’s best to use a powerful explosive like a Grenade, Mine, or Claymore. A very close shotgun blast can also clear the Keep It Clean research task for
