This PC-exclusive mod for Doom II: Hell on Earth, released in 2015, presents a unique design challenge that shapes its entire experience. Developed by Marcaek, it features a megawad comprising 18 levels, all constructed with a strict limitation: only three specific wall textures are permitted throughout the entire project. These core textures are DOORTRAK, FIREBLU1, and GRAYTALL. The objective was to create visually appealing and engaging environments despite this severe constraint.

While the primary textures are limited, each map was allowed to incorporate one additional flat texture of the author's choice, alongside the standard F_SKY1 for the sky. Furthermore, non-visible surfaces, such as the upper and lower textures of one-sided lines, could utilize further textures. This was primarily for functional purposes, like implementing switch sounds or creating sky transfers, rather than for broad aesthetic application.

What is the core gameplay experience?

The core gameplay revolves around the classic Doom II shooter mechanics, emphasizing fast-paced combat and exploration. Players navigate through 18 distinct levels, facing familiar demonic hordes and utilizing the arsenal provided by the parent game. The unique texture limitation forces a different approach to level design, potentially leading to distinct visual patterns and spatial awareness challenges.

What makes this mod unique?

The defining characteristic of this mod is its extreme texture constraint, utilizing only three specific wall textures across its 18 levels. This limitation, combined with the allowance of one custom flat per map and specific uses for non-visible textures, creates a focused and distinctive visual identity. The challenge for the developer was to craft varied and interesting gameplay scenarios within these strict aesthetic boundaries.

How does this mod relate to the original game?

As a mod for Doom II: Hell on Earth, it builds upon the established engine and gameplay. Players familiar with the original title will recognize the core shooting mechanics, enemy types, and movement. This mod offers a new set of levels and a specific design philosophy that differentiates it from the base game and other mods.

What kind of atmosphere can be expected?

The atmosphere is largely dictated by the limited texture palette. The reliance on DOORTRAK, FIREBLU1, and GRAYTALL suggests a potentially stark or industrial aesthetic, with the specific arrangement and use of these textures influencing the overall mood and visual feel of each level.
