Biohazard

Biohazard font is a free font with a jagged, eroded look that feels wet, unstable, and slightly toxic. The narrow, black forms create a rough horror-movie rhythm, making it a strong fit for posters, game titles, album art, Halloween flyers, YouTube thumbnails, and underground brand graphics.

Biohazard works best when you want instant atmosphere without adding much extra texture around it. This free font brings grit to event promos, indie film headers, zines, packaging, and spooky social posts, and it pairs well with a plain sans serif to keep layouts readable while the headline does the dirty work.
