Eviternity

Eviternity is a 32-level megawad for Doom II using MBF-compatible source ports, created by Joshua O'Sullivan (Dragonfly). It was released on December 10, 2018, the 25th anniversary of Doom's release, alongside the OTEX texture pack by Ola Björling (ukiro), which the WAD uses exclusively.

Eviternity began development in March 2018, with much of O'Sullivan's design process being livestreamed on Twitch. Several guest mappers were also brought in to help fill out the map roster. The WAD is divided into six episodes—referred to internally as chapters—each with a distinct theme showcasing OTEX's versatility. The final version was released on February 10, 2019, and was simultaneously uploaded to the idgames archive. A sequel, Eviternity II, was released in December 2023.

Eviternity received critical acclaim from the community, and the next year it would also receive of the 2019 Cacowards. In 2023, Eviternity was included in Doomworld's Doot Eternal music feature for Doom's 30th anniversary.
