Titanfall 2 is a spiritual game

Titanfall 2 is actually a decently spiritual game.
You get this perk where you completely disappear by phase shifting into the astral realm quickly.
When you do, you disappear to every one else.
To you, you're exactly where you are but everything is black and white.

Which brings me to mention a game called limbo. It's about a kid who goes into limbo to rescue what is meant to be his sister from the afterlife. Look how they portray limbo (the astral dimension). The ENTIRE GAME (astral dimension) is shown as black or white!

The point I'm trying to make is that the astral dimension is actually another three dimensional world. And if there's another 3 dimensional world how many more are there?
As many 3D worlds that make a 4D shape like the hypercube. Each face (cube) is another 3D world!

Which is also reflected in the different spirit realms!
