This is a mod for Doom II: Hell on Earth, released in late 2022 for PC (Microsoft Windows). It offers a significant expansion with a thirty-five level mapset. The design draws inspiration from various sources, including other Doom mods like Back to Saturn X2 and Hell Revealed II, as well as elements from Final Fantasy, Castlevania, Ninja Gaiden, Metroid, Resident Evil, and Mega Man. The mod aims to provide a distinct experience through its environments and narrative.

Story and Setting

The narrative is set on the planet Elysia, where UAC personnel and demonkind have coexisted for decades. This period of peace is disrupted when a meteor impacts Mount Esthar, the largest volcano in the demon realm. An alien parasite emerges from the meteor, infecting the demon population. Subsequently, Mount Esthar erupts, spreading a corrupting influence across most of Elysia and eliminating the UAC presence. The player's mission involves traveling to Elysia to search for UAC survivors and to eliminate the alien parasite.

Unique Features and Core Gameplay

This mod distinguishes itself through extensive modifications to sprites, sound effects, and enemy behaviors via dehacked changes, all integrated to support its narrative. The developers have incorporated source port extras, such as GLDEFS for enhanced visuals, custom obituaries for defeated monsters, and edited menu graphics. The ending cast call also features additional enemies. While each of the thirty-five maps is designed to be pistol-startable, a continuous playthrough is recommended for the intended experience.

Gameplay Modes and Difficulty

Corruption offers multiple difficulty settings to accommodate different player preferences. The standard "Normal" mode is presented as the intended way to play. Additionally, "Medium" and "Easy" difficulties are available. For players seeking a greater challenge, an "Xtreme" difficulty, described as Ultra-Violence Plus, is included. On ZDoom ports, a special "OHKO" (One Hit Kill) mode is present, where both players and enemies are instantly defeated by any damage.

What makes this mod stand out?

The mod's appeal stems from its comprehensive overhaul of the Doom II experience. Beyond new maps, it features significant alterations to the game's presentation and mechanics. The integration of diverse inspirations, from classic JRPGs and action games to other Doom mods, results in a distinct atmosphere and gameplay feel that moves beyond a typical mapset. The attention to detail in visual enhancements, sound design, and narrative integration contributes to its unique value proposition for fans of the genre.
