On Trauma Center: Under the Knife. *caution, some spoilers ahead!* I'm still stuck on 3-4: Something Precious; the operation where you deal with the Deftera strain of GUILT. That's the one where there's two masses, one red, one blue, and you have to drain them when they merge together and make a yin-yang sort of thing. There's one "set", if you will, in the patient's stomach, and two "sets" in the lungs. This is where I am stuck. When I start, I can get through the stomach operation with little or no fuss. When I get to the lungs, I'm juggling zapping the tumors with the lazer while trying to get red-blue "set" to form. The problem is masses of the same color bumps into one another frequently, making my vitals drop severely. By that point, my vitals get so low that I barely have a chance to drain and excise the GUILT before the patient dies. It doesn't seem to matter how much stabilizer I inject either. I pulled up a walkthough and it suggested spreading a ring of antibiotic gel around a "set" to prevent like-colored masses from bumping into it and dropping vitals, but that hasn't helped much. I got close once, and I was barely starting to excise the first set when the patient kicked the bucket. Anyone else out there that's played the game, what did you do?
