And then, there are the P-Eternal ranks. If a P-rank is a testament to skill, a P-Eternal rank is a testament to madness. To achieve this, the player must not only P-rank a level but do so without using any of the game’s "crutch" mechanics—no revives, no full-health resets at certain checkpoints. It requires an absolute, flawless run. A 100% save file whispers the silent, terrifying truth: this player has done things that border on the inhuman.

A 100% save file means every single level in Acts I, II, and the Prelude, plus the hidden Prime Sanctums (Soul Survivor, Sisyphus Prime), achieves this P-rank.
