A heavy, blocky sans built from rounded-rectangle and superellipse-like forms. Strokes are consistently thick with softened outer corners, producing squarish bowls and counters rather than circular ones. Curves transition quickly into flats, apertures are relatively tight, and terminals are mostly straight-cut with occasional stepped or notched details in places like the S and some diagonals. The overall rhythm is dense and sturdy, with a slightly mechanical feel and clear separation between characters despite the compact interior spaces.
Best suited to display sizes where its compact counters and chunky geometry can read clearly—headlines, posters, packaging, esports and gaming interfaces, and bold brand marks. It can also work for short labels and UI headers, especially where a sturdy, techno-industrial voice is desired.
The font conveys a bold, engineered tone that reads as modern and utilitarian. Its squared, softened geometry suggests retro-futurist and arcade influences while staying clean enough for contemporary tech and sports branding.
The design appears intended to deliver maximum impact through compact, rounded-square geometry: a contemporary display sans that nods to industrial signage and retro arcade typography while keeping a clean, monoline construction.
Distinctive letterforms include a boxy O/0 with a rectangular counter, a Q with a short, straight tail, and angular diagonals in K, X, and Z that emphasize a constructed, modular look. Numerals share the same squared, softened geometry, helping headlines and short numeric strings feel cohesive and intentional.
