In most science fiction, "subspace" is used to refer to a projected or inherent three-dimensional physical area where the laws of physics function differently than in the rest of the universe. In REKT, however, the concept is quite different, as subspace is merely a fictional concept: fields of altered physics cannot be projected. There are, however, two separate concepts that are somewhat similar (and, indeed, accomplish roughly the same thing. These two concepts are "physics bubbles" and "multispace".

Physics bubbles

Physics bubbles are inherent in matter that comes from other universes, such as anomalous materials. These materials never fully "leave" their home universe, and are therefore never fully subject to our laws of physics. They may exhibit unusual properties - increased tensile strength and higher heat radiation are two examples. It is typically not possible to destroy a physics bubble without breaking down the material's molecular structure; the atoms decay rapidly after that and stabilize only when reduced to stable particles that also exist in our universe.

Partial physics bubbles

Some anomalous materials (such as veloxium) are more strongly integrated into our world than others, and require specific conditions to function. These conditions may include temperature, lighting, oscillation, electric charge, or electromagnetic fields, to name a few examples. When put into these specific conditions they tend to function much more powerfully than materials in normal physics bubbles, implying that their home universes are much more removed from our own.


Multispace is a new concept that hasn't been around long - no more than a decade at most. It has only been seen to be exhibited by Quantum technology.

In some aspects of Quantum technology such as "Quantum Metal", a three-dimensional area of space can exist in multiple universes at once, with multiple copies of the same material occupying the same physical space. The nearest analogies we have are "quantum stockpiling" and "clipping", both of which generally apply only to video games. It is currently unknown how multispace is created, but it seems to last indefinitely. It is worth noting that the physical strength of a material in multispace is greater than the sum of its parts - that is to say, a five-layer bar of iron that exists in five universes occupying the same space is notably stronger than five times the strength of a single bar of iron of the same size.

When there are empty areas in a multispace field, inserting normal matter from our universe tends to split it into multiple pieces, effectively shredding it. This accounts for the consoles that "ate" fingers and hands in Mission 1. In addition, looking at such a field has strange effects on normal vision, making the space therein seem to "bend" or "shift" in a manner similar to those produced by optical illusions. It is theorized that this is due to our brains not knowing how to process the visual information.
