Double Impact is an episode replacement PWAD for The Ultimate Doom by Matt Cibulas (RottKing) and Ralph Vickers (Ralphis). It is a winner of 2011's 18th Annual Cacowards and requires a limit-removing port to play. In its original PWAD form, it replaces all nine levels of Episode 1. On November 11, 2013, Double Impact was included with Freedoom: Phase 1 as part of the fourth episode of that game.

On February 13, 2020, Double Impact was the first community-made mod to be adopted by Bethesda as one of the official add-ons for the Doom Classic Unity port. This version is slightly different. First, the intermission image, which incorporates the cover art from the unlicensed Hungarian novel Doom - Tisztítótűz, was recreated using instead the Eisen character from Quake Champions (specifically, the Eisen skin variant featuring a cap and an eyepatch). Another difference involves the alteration of the d_e1m8 theme to remove references to the theme of Doom 64's main menu.
