This is the last operation in the game. They've even given you the awesome final boss music so enjoy it!
The difference between Derek and Naomi here is substantial compared to the other operations, but we'll get to that later. For both of them, your objective will be to get Savato down to its knees as fast as you can.
A problem with this operation is that it's so long that after a while you'll likely have some trademark Trauma Center jitters and wrist pain. It's important to get a few minutes of rest in between retries. It's also a good idea to pace yourself throughout the operation because as your wrist stamina gives out you'll get worse and worse. Try to relax your grip a little when there's a slight lull in the action. Be careful though, because if you've been gripping the wiimote for a long time and suddenly relax and then tense up again, there's a chance you can get mild tendon spasms which can be a little offputting. You can also pause the game in the middle of the operation and rest for a few minutes. This is pretty effective in getting your wrist back in the game. Obviously I can't do that in the video, which sucks and it really shows at the end. Hell, I even botched the final suture on Derek and got a GOOD. But oh well what can ya do. Not all of us can be legendary surgeons with wrists of steel.
Get inside. You'll be at the heart and spot the Savato plus a bunch of its webs. You'll want to immediately switch to the scalpel and start severing those. Just put your cursor over a web and keep the button held down on it for a few seconds. However, your scalpel will melt each time you break one. A nice thing to do here to get through these webs fast is this: use your scalpel on the places where two strands intersect. This will make it so that you cut one, and severely weaken the other. Then, while the scalpel is recovering, put the cursor over the strand you weakened and alternate between pressing the Z button and the B button quickly. This will activate the scalpel in very, very short bursts even though it's unusable. However, since the strand has already been weakened so much, this short burst is all you need to cut it. With this tactic you can cut two webs per scalpel. In fact, since the first web only has 4 strands, you can sever them all before Savato has a chance to create new ones or bring out minions.
Once they're all severed Savato will move on to the bottom of the heart and create more webs. You'll have to keep severing them in the same way. Now here, he may create either 5 webs, or 4. I'm not really sure what the deciding factor on how many he makes here is. It seems to be random. However, if he only makes 4 you luck out because you can sever them all before he gets a chance to create a new one just like in the first web. If he makes 5 you'll have to deal with one new strand and some minions before you can scalpel the last one.
Obviously you want to burn these little guys with the laser but you should do that ONLY if your scalpel is currently unusable. As SOON as you can use your scalpel, ignore the mini-savatos and sever a web. Then go back to burning them with the laser as the scalpel is recovering. As soon as it is, cut off the last one. Savato will escape again to the top of the heart and create a bunch of new webs. You'll have to repeat the same procedure to get rid of these, except this time there'll be more so he'll get a chance to make new ones and minions. Just remember the rule: only laser the minions if your scalpel is currently unusable.
The transition from top to bottom and then to top again here is a great place to rest for a few seconds. It's not much, I know, but every little bit helps. Relax and place your hand on your lap or wherever you feel comfortable until you can use your tools again.
Make sure all the mini-savatos are dead before you cut off the last strand. When that's done you'll move on to the next phase. Here you will have to keep using the laser to burn the Savato's outer layer. Since he likes to dodge a lot, what I recommend here is that, instead of holding the button down, you try to prick him for a second with it, and when he dodges, follow him but WITHOUT holding the button down, and only use the laser when he's reasonably immobile. Basically, you want to avoid wearing out the laser. One, because it's actually less effective than using it moderately, and two because you want to keep it on hand in case he decides to send out minions. Still, there are a few times where wearing out the laser completely could be good. For example, if it's already in the red, and Savato has just sent out his minions and you've burned them all off. Wearing it off completely before suturing the laceration and then injecting stabilizer once could very well work in your favor.
Right, minions. That's one of his two modes of attack. He'll periodically create a long laceration from which little guys will pour out of. You'll want to get them with laser immediately before they get a chance to disperse. Then suture the laceration before going back to the offensive.
The other mode of attack is simply to cause 3 normal lacerations. Just suture them as fast as you can before going back to the laser.
The strategy I recommend here is to be very aggressive. If the laser is white, you should be burning Savato. ONLY give the laser a break when it's yellow-red. Don't let it sit there unused if it's completely recovered. When it IS recovering you should be pumping stabilizer. That's the strategy. Never let up. Even if vitals aren't at max, if the laser is white forget about the syringe until it's yellow. In fact, sometimes it can even be better to completely ignore vitals unless they're really low and just try to get that shell off as soon as possible.
The exception to this, of course, is his attacks. Killing his minions and suturing lacerations always takes priority over everything else, in that order. And the exception to THIS is, of course, if the patient is about to die, ignore everything and concentrate on getting vitals out of the teens.
Be mildly careful when suturing lacerations in this phase. Remember that you need a chain of 200 for the XS, so try not to get a BAD before that.
When you've laser'd off the outer layer, which you will know because Savato will start doing some crazy ninja dodging when you try to laser him some more, it'll be time to switch to the scalpel and slash him once. He moves around a lot so be careful. When you do that, he'll escape down to the bottom of the heart, and you'll have to repeat the procedure again. If you've been very aggressive you can get him to move out to the bottom before the clock goes below 8. Of course this also depends a little on how aggressive HE is acting. Sometimes he attacks so much that you can't help but take longer. Don't worry about it. Repeat the procedure in the exact same way and make him move to the top again. Now this will be the final round. Here I'd recommend to be as aggressive as you've been up till now and get his outer layer off as soon as possible, then cut him up. Now he'll be vulnerable. In a best case scenario the clock should be over 6:30. But the actual time limit is 1:30, so if you took a couple minutes longer, don't sweat it. Raise vitals to higher than 30 if necessary, then inject the black serum into him. You may be tired by now. Be careful and make sure you don't get a miss.
Now Savato will go balls out. This is the phase in which you're going to stall to rack up points for the XS. Right after you inject the serum, he'll create 8 lacerations and automatically bring down vitals to 30. Here Derek will automatically activate his Healing Touch. If you're fast, though, you can inject almost a full syringe of stabilizer before it gets activated.
Now Derek's Healing Touch might not be as broken as Naomi's since it doesn't heal automatically. However, it slows down time more so he can definitely hold his own. What this means is that Savato will create lacerations at a much slower pace than if he were under the influence of Naomi's Healing Touch. What you're going to do is start suturing lacerations as fast as you can. You should already be over chain 200 so don't worry too much if you get a couple BADs here and there. Since Derek's Healing Touch doesn't heal, the only way to raise vitals is by injecting stabilizer. Therefore, you'll want to inject a round or two in between Savato's attacks. I recommend suturing lacerations while he's in the middle of his attack, and only inject stabilizer after his attack animation has ended. The reason is because it seems the syringe gets slowed down if you use it during the animation, but the sutures do not.
If you suture reasonably fast, then you should be treating the lacerations faster than Savato can create them. Therefore, after a little while, you will have more time to inject stabilizer. This means that you can slowly raise vitals all the way up to 99 during this part. How long should you keep stalling in this phase? It's up to you. The longer you keep doing this, the higher your score will be. The time limit is 1:30, so if you wanted to get the highest score possible you'd stall until around 1:45 or so. Of course, this is far from necessary. If you want to end a little sooner feel free to do so. I had no choice but to end sooner myself, since youtube has a video limit of 10 minutes. In any case, once you're satisfied, simply activate the ultimate Healing Touch. Now time will stop completely. Suture ALL of the remaining lacerations. When that's done, inject a FULL syringe of serum into the Savato. Make sure it's full. Otherwise it won't work. That'll be it. Vitals should already be at 99.
All that'll be left is the final suture and bandage. Chances are your wrist is very tired by now. I know mine was. Just look at that sorry excuse for a final suture. It might be a good idea to pause the game for a second here to get your bearings back, not to mention get the feeling back in your wrist. The final suture here is actually a little weird. Normally you'd make the lines wider than the opening, but that seems to only net you a GOOD here. To get the cool you actually have to make very narrow lines. Narrower than the opening. Check my Naomi vid to see what I mean. Not the Derek one though because I suck and got a GOOD there. Still, it doesn't actually matter if you get GOODs or BADs here, as you should have way more points than you need. However, if you get a miss you can forget about getting the XS.
