Final Boss Phase 3 Optimization

Observing Tychoon during Knaus's section of the final fight, I wondered if it could be possible to exploit his behavior. My initial tests show some potential.

Important discoveries:
1. The objects Knaus needs to blow up have a set order in which they are primed for demolition.
2. When you drop dynamite, Tychoon will try to come out of the porthole closest to it and attempt to vacuum it if he can get to it before it explodes.
3. After vacuuming dynamite, the porthole it comes out of is deterministic and can be manipulated.

Use this crude picture I drew as reference: http://i.imgur.com/Dk2ipBo.png

The targets of destruction are numbered in order. The portholes are labeled A through H.
In most cases, Tychoon will teleport the dynamite to different places depending on which way he is facing out of the porthole when vacuuming. These directions are labeled with arrows and subscript 1 and 2. Portholes C and D are the exceptions. They will always teleport to F and E, respectively.

The chart on the right shows all porthole inputs and outputs. From these, we can extrapolate generic zones where dynamite will be teleported to one specific porthole output from anywhere in that zone. These are circled and labeled.

Now, knowing all of this information, how can we abuse it in the demolition sequence?

Object 1 is a freebie. Tychoon offers no resistance when walking to it and destroying it.

Next, get Tychoon to vacuum a dynamite to porthole F and destroy object 2 while you place a second dynamite next to object 3.

The next target, object 4, would suggest dropping a dynamite near object 5 so it can be vacuumed and deposited at porthole A, but the dynamite ejections from portholes A and B are quite forceful, and usually land next to E and F, respectively. So it seems like destroying 4 manually is the best option unless some more trickery can be found.

Next is object 5, with porthole F conveniently next to it. Drop a dynamite at object 6 and it should be delivered to 5, then drop another dynamite next to 6 to destroy it.

That leaves 7 and 8. As stated before, I don't see how to get a dynamite to explode next to porthole B, but if that can be discovered, dropping it to the left of G is the best bet. 8 of course would be demolished last with no help from Tychoon.

Route for Phase 3 of Final Boss

*Below you'll find a description as well as both an image and a video of the route I use for the third phase of the final boss fight. Credit to BoursinBurger for all the research, and coming up with the initial route which this is based on.*

*The big discovery BoursinBurger made, was that when your dynamite is sucked up by the boss, which manhole and even which direction it's spit out at is in fact not random. We use this knowledge to help us blow up the third and fifth target (the ones on your left and right when you first enter the room) without having to go anywhere near them.*

*Note that the direction dynamite is sucked up from in relation to a manhole, affects where it gets spit out. As such the placement of dynamite at certain points in the route is important, and these cases are underlined in the description below. You can also refer to the image near the bottom to see exactly where you need to place your dynamite.*

*This route is quick, fairly straightforward, and the most consistent approach I have found. It has some timing to it, but nothing too precise or difficult. There is also some slight variation with the dynamite being sucked up which can occasionally lead to misses and sometimes be hard to identify quickly, but this is rarely a concern.*

This entire strategy takes place on the upper level of the room:

**1.** Go through the crawlspace on the right and place dynamite next to target 1.

**2.** Quickly run to the right edge of the upper level and drop dynamite off the edge. This will hit target 2 during the short cutscene that plays after blowing up target 1.

**3.** Run to target 7 and place dynamite **down-right of the manhole** here. This will be sucked up and hit target 3.

**4.** As soon as the previous dynamite is placed, quickly run over to target 4 and place a dynamite here. If you are fast enough this will blow up before the boss has a chance to suck it up.

**5.** Run to the manhole left of target 8. The boss will pop out and attempt to throw a wrench at you, wait a moment and then place dynamite **down-left of the manhole**. This will be sucked up and hit target 5.

**6.** Once the boss finishes sucking up the previous dynamite, drop another one off the left edge to hit target 6.

**7.** Run to target 7 and either place dynamite here, wait for the boss to suck it up, and then place another, OR place the dynamite, quickly run to target 8, and place dynamite here as well to bait the boss into sucking up that one instead.

**8.** Depending on which approach you used for target 7; run to target 8 and place dynamite, or simply put another one down if you're already there.
