Correction, 29 October 2026. The first version said Buffer Underrun has no weapons, named a Kilobyte tier that does not exist, and quoted untraced sizes and distances. Those are corrected below. The first version remains readable in the journal's public history.

Exhibit 1 — Inside Buffer Underrun (base:buffer_underrun) rendered in a clean 16:9 no-HUD viewport: glowing allocation spheres and numbered memory blocks (1, 4, 7, 14, 16) drift across the curved turquoise grid while rival processes manoeuvre in the background.

Exhibit 2 — The player's glowing yellow allocation sphere on the open memory floor; the floating numbers are hit values from fighting nearby.

If you walk up to the portal frame at the far end of the Antechamber and wait a beat, the archway does not show a painted loading screen. It opens a live view of the arena on the other side, where glowing spheres and numbered memory blocks drift across the tile seams.

Stepping through into Buffer Underrun, with the viewport cleared of HUD chrome, what is left is scale. You start as a Sub-Byte, a glowing allocation sphere barely taller than the grid squares under your feet (Exhibit 1).

The aim is to grow:

• Grow from Sub-Byte to Byte (at 50 allocation), then Word (150), Block and Page, by reclaiming smaller numbered blocks and processes scattered across the floor.

How Scale Changes the Fight

Every glowing sphere and numbered block on the floor carries an allocation value. Touch one smaller than you and it folds into your process: your allocation climbs and your sphere grows.

Roll into something larger than you and it will not fold in; you have to grow first. What was an obstacle at the start becomes food once you have reclaimed enough to cross the next tier.

Buffer Underrun is not weapon-free. Each tier raises your weapon level, and you can fragment a rival's buffer with fire as well as absorb it on contact; the floating numbers in Exhibit 2 are hits. Absorption is simply the part this post is about.

One thing makes the loop readable without a HUD:

• Every memory block wears its value as a number on its hull, so you can read the risk and reward of the floor with the HUD hidden.

A good test of a simulation engine is a doorway into a different set of rules. If stepping through into a room where you grow by rolling up glowing memory blocks feels crisp and readable, the foundation under the rest of the catalog is doing its job.
