Our take on Rule No. 1

The warm-up framing understates the repeated-run structure: the core activity is fighting wave after wave while chasing a higher score. Its compact scope suits short sessions, but players expecting a broad shooter campaign may find the format limited.

What is Rule No. 1?

Rule No.

1 is a fast arena first-person shooter focused on shooting feel and high scores. Players fight successive waves of sentient metallic shapes and accompanying monsters while trying to improve each run. The game includes light roguelite elements and is presented as a short activity for warming up or waiting for another download. Its protagonist, Rule, is a voiced heroine with a sarcastic and slightly crude personality. Progress involves repeated failures followed by eventual victories, with score chasing as a central goal. The game also includes a hidden first rule that players discover by playing.
