A Sludge is basically an particularly aggressive blob of the Sprawl that you'll observe spreading across every Hot-Zone in Rainbow Six Extraction. The Sludge is a low-level enemy, and so information technology more commonly spawns on Moderate Threat Level, just its appearances are e'er random, so you might demand to try a few incursions earlier you encounter one.

The 4th ready of Report objectives in the San Francisco region, Caustic Buddies, focuses on the Sludge, and one of those objectives, Keep It Clean, tasks yous with killing a Sludge without it dividing. You've probably encountered Sludge up to this point in the game, and noticed that it always divides when you damage information technology, so you might be wondering how it's possible to foreclose information technology from dividing. Well, similar a lot of things in Rainbow 6 Extraction, information technology's simple when yous know how.

While bullets fired by rifles, pistols, submachine guns, and lite machine guns will all cause a Sludge to divide, a well-aimed, close-range, direct hitting from a shotgun will kill it outright before information technology starts getting any funny ideas about starting a threesome. So, if you're trying to complete this report, always select an Operator with a shotgun. Make certain you lot get up close to the Sludge and aim downward sights to make sure you get it right in the center. A glancing accident from a shotgun shell might cause information technology to divide.

If you prefer picking off targets from long range and don't desire to take a shotgun, you lot tin also kill a Sludge with an explosive to forestall it from dividing. We institute a Sludge on the ceiling and placed three Claymores underneath it (merely to be sure), then shot it in one case with a pistol to make it drop downwards. See the sequence of screenshots below for a visual, accident-past-blow account. It was overkill just very effective. You could likewise apply a Fragmentation Grenade, Nitro Cell, or Arc Mine, but each option is more excessive than the terminal.
