- “This is like the fountain all over again. Why aren't you stopping this?”
- — Trish, approaching Cole about the situation
As there was a bunch of sick, tar-covered civilians lying helplessly along the sidewalk, Trish approached Cole, asking why he was not stopping the contamination. Cole explained that he already destroyed a tanker full of tar before, but this pollution was caused by another source. When Cole contacted Moya about the issue, she explained that the water towers on the rooftops were the only known source of the contamination. After clearing out the Reapers surrounding the first water tower, Cole noticed a keg attached to it, with tar dripping from it. Moya ordered Cole to destroy it, as it would prevent the spread of the black tar.
Good karma: After destroying the first keg, Cole ended up with tar on his face, temporarily disabling some of his battery cores. Cole made his way to the other rooftops to clear out the enemies and then destroy the remaining kegs.
Evil karma: Instead of destroying the keg, Cole overcharged it, causing more tar to release into the system. Moya advised him to destroy them instead, however, Cole continued to overcharge the kegs, releasing more and more tar into the system and making more people sick in the process. This, in turn, made Moya furious at Cole. Trish even took notice and called Cole out on his selfish actions. Cole tried explaining to her that it was the only way he could get them off the rooftops, which she rubbed off as nonsense, noting how he was only making things worse and that they were better off without his "help."
Once the task was finished, a strange man decked in white clothes and equipped with metallic implants teleported in front of Cole, saying that Sasha was not going to be happy about him destroying the tar kegs. The man then leaped towards Cole and dug his icy cold fingers into his face to show him a vision. Cole was shown horrible things he could not even properly begin to describe. He was then released from the stranger's grasp and although Cole did not know who the man was, he just knew that the man was responsible for everything and that somehow, the Ray Sphere was involved in it. The mysterious man then disappeared.
Use your minimap to locate each tar keg. They are marked by the yellow dots. Each one will be surrounded by a group of Reapers you will have to defeat before destroying the kegs. Keep in mind that there are sick civilians that will appear on these rooftops as well, so you should be cautious as to how you defeat your enemies. It is possible to try and heal them with Pulse Heal, but the effect is useless. Also, Cole can still be attacked by infected people, but will still gain evil karma by attacking them. Being hit by them temporarily causes Cole to experience hallucinations.
When you approach each keg, you will be presented with a karmic choice, in which you can either destroy the keg using Shockwave or overcharge it using Lightning Bolts. Overcharging it will not destroy it, but will cause more contamination among the civilians. Destroying it will cause Cole to get lathered with tar, temporarily disabling some of his battery cores and some of his powers.
Note: Just like during the mission "Mind Games," Trish makes an appearance in-game as an NPC, and directly hurting her in any way (using any of Cole's powers) fails the mission. However, Cole can hurt Trish indirectly by throwing a car on top of her, and the mission will not fail.
