This Triti can be a very hard operation because if you work too well and don't let any membranes multiply, you will not get the points needed for the XS. The trick lies in looking at what exactly gives you points in this operation. There are two things that give you points. Removing membranes and draining gas. But draining gas gives many more. Therefore our strategy will consist in draining as much as possible. The score you need for XS is 6400 points. Read on to see how to do this.
In case you missed it the first 3 times, I'm going to paste the Triti explanation again:
Triti is made up of two parts: membranes and thorns. What you want to do is remove all of the membranes from the pancreas. However, each membrane is embedded into the organ by three thorns in each corner. To remove a membrane, first you must remove all of the thorns surrounding it. The thorns also regenerate after a few seconds.
The big problem, of course, is the way the membranes multiply. First of all, notice that membranes only multiply based on what you do. Notice that if you don't do anything, they will never multiply. This means that, while speed is still important, it's also important to know what you are doing.
Notice that membranes can only multiply when you remove one with the forceps. Simply removing thorns does not allow them to. Now, the trick to Triti's nightmarish multiplication is simply this: if there are two thorns adjacent to each other, and there is a free space next to them, a new membrane will appear there when you remove a membrane on any part of the organ. Therefore, the trick lies in looking at the thorns. What you want to do is only remove membranes when there are no adjacent thorns currently present. The exception is when there is no free space where two adjacent thorns can create a new membrane. This is either because there is already a membrane there, or because it's the edge of the organ and there is no actual room for a membrane to appear.
You're going to be using your forceps almost exclusively here. I recommend that you grab the wiimote in a specific way here: place your thumb over the A button and grip the remote firmly with it. That's right, you're going to have the A button constantly pressed throughout this operation. Never let go of it until you're done. If you have the A button pressed, then you can simply use the B button to grab and let go of things with the forceps. There is no need to press and let go of both buttons. Using a single button affords much greater control over the remote. When pulling thorns in general, remember that they are embedded in the organ. You want to pull UPWARDS when grabbing them before placing them on the tray. If you simply pull to the right, you will get a miss and forfeit the entire operation. This is important, so always remember to pull in an upward motion.
Now what follows is the way to XS this specific operation. Understanding Triti and the meaning behind what you're going to do is good, but if you follow these directions you can XS the operation without having to understand it:
What we're going to use as a point of reference here are the rows of thorns. If you look at them horizontally, there are 5 rows of them. From top to bottom, row 1 has four thorns, row 2 has three thorns, row 3 has two thorns, row 4 has three thorns, and row 5 has two thorns.
As soon as you can use your tools remove the two leftmost thorns of row 1, and the leftmost thorn of row 2. Then remove ALL of the thorns in row 4. Next, remove the two remaining thorns in row 2. It's important that you remove them in that order. Now quickly remove the two membranes in the upper-left corner. No new membranes should have been created when you do. Now, don't stop for a second and remove the two thorns at the very top. Then very quickly remove both of the membranes in the upper-right corner. Now you can drain any gas that may be floating around.
Now there should only be 5 membranes left and no new ones should have been created. Raise vitals for a bit and let the thorns regenerate. Now remove ALL of the thorns except for the two at the very bottom. Then pick up the two top membranes. Ignore the gas for a bit and quickly remove the thorn on the right, followed by the rightmost membrane. Drain the gas now.
Time should be around 4:30 and now there will only be a measly 2 membranes left. However, if you remove them both you will not get the XS. Therefore we're going to use the following strategy: notice that draining gas gives you points! When you've gotten Triti down to 2 membranes, rather than letting it multiply, you can simply remove those 4 thorns over and over and over again, and there's a very, very high chance that at least one of them will turn into gas every time. You can keep doing this as long as you want before going in for the kill. The longer you keep doing it, the higher your score will be. You don't really need to do it that many times for the XS though. I'd say a bit less than 10. When your chain is at 60 you can probably go ahead and kill it.
Look at the video for the demonstration of the directions I gave you plus the draining strategy at the end.
