Route Walkthroughs & Info

Basics/Info

All previous route videos will be kept on this page for future reference. These old route videos could be used for beginners who don't want to jump straight into the fastest strats, or for anyone who is interested in the change in the routes over time.

WydD has a lot of tech/strats videos on his channel here for various rooms where he explains in-depth a lot of the specifics of each strat.

Lag/Lagless Explanation

Lag and lagless apply to every category, so I will describe the difference here, in reference to Any%, instead of breaking each category section into two. Because of cube chambering being discovered, lag and lagless are no longer separate sub-categories but rather are able to be compared on the same leaderboard.

Lag

Lag was originally found by watching a first playthrough livestream where the broadcaster was lagging and ended up with cubes in The Chase. We then went about trying to figure out ways to cause lag. The first method found was to create a large hollow cube so the game lags while it fills in. A run using this original method can be seen here. It then progressed to making a much smaller cube and picking up some from the middle of it while it tried to fill itself in, as shown in this run. I'm not quite sure how, but we eventually found that alt-tab (as well as alt-enter, or F11) also causes lag, so the run progressed to the way it is currently.

In order to cause lag using the alt-tab method, the inputs are as follows: Without letting go of Alt, hit Tab, release Tab, hit Shift, hit Tab, release Tab, release Shift, hold W, and finally release Alt.

For the alt-enter method, the inputs are basically the same but are listed here: Without letting go of Alt, hit Enter, hit Enter again, hold W, and finally release Alt.

For the F11 method, all you need to do is double-tap F11 and then hold W. Although this method requires less button presses, it can still be slower for your machine to recover from than alt-tab or alt-enter.

The F11 method is allowed to be rebound to another button (extra keyboard or mouse macro buttons) because it is a one-button method. The other two methods of lag are not allowed to be bound as a macro.

Use whichever method your machine recovers from more quickly, unless you have to play in windowed mode since alt-tab lag is only possible in fullscreen. If you have to play in windowed mode, then you have to use alt-enter or F11 lag (or alternatively, one of the older methods described above).

If you're running on Mac, then you will need to follow this guide to set up lag glitch. If you're running on Linux, then we don't have a method yet, feel free to contact me if you find a method for Linux (not including the old "make a hollow cube" methods).

Also, as described here, SDA will not accept runs utilizing alt-tab (and likely alt-enter) lag. If you intend on doing a run for SDA submission, then you will have to use old lag methods (unsure if those are allowed by SDA), or use lagless. SDA also uses a different timing method - the timer would start as soon as you gain control after deleting save, in the main hub, and timing would stop when the game fades to black after the cutscene.

Lagless

Lagless was the original Any% route pre-lag discovery. An original run can be seen here or here. After lag was discovered, lagless stayed the same as it was for quite a while until this discussion happened, at which point Grey Acumen found the cube chambering glitch - the original video of which can be seen here.

Cube chambering can be performed as follows: Have cubes in the gun or be holding right mouse picking up cubes, hold left mouse while still holding right mouse, walk through a field of any size, release right mouse while still holding left mouse, finally release left mouse. Be sure not to accidentally pick up a cube you've already gotten through a field while trying to cube chamber another cube.

Hub Storage Explanation

Here's a video from GamerDudeK including a tutorial on how to do HS and explanation on how/why it occurs. You can ignore the lag/lagess info above when using HS. Lag used together with HS is slower than lagless, however lag can be used to "buffer" HS in order to allow you more realtime to scroll/fire more cubes. Ideally, you want to be able to do HS lagless ("unbuffered").
