This PC mod for Doom II: Hell on Earth, released on December 25, 2024, is built upon the MBF21 engine. Its design is centered around a strict 300-line limit for each map, a constraint that influences the intricate level design. The creation of each map was a collaborative effort between two map authors, contributing to a variety of environments and gameplay scenarios.

A distinctive feature of this mod is its branching path system. Most maps offer two distinct exits: a "naughty" exit and a "nice" exit. The player's choice of exit directly impacts their progression, leading to different aesthetics and gameplay challenges within the same map. This design allows for up to three different endings across the mod's four primary maps, encouraging replayability and the exploration of all potential outcomes.

What is the core gameplay experience?

The gameplay is rooted in the classic first-person shooter genre, requiring precise aiming and strategic movement. Players navigate through environments, engage various enemies, and manage resources such as ammunition and health. The 300-line limit per map fosters focused level design, often resulting in compact yet detailed arenas that challenge a player's ability to adapt to immediate threats and environmental layouts.

What makes this mod unique?

The standout feature is the "Naughty or Nice" branching paths, which significantly enhance replayability. Unlike mods with linear progression, this title provides a dynamic experience where player choice directly influences the journey. The dual versions of maps, each with its own visual theme and enemy placement, ensure that revisiting a level can present a fresh challenge. This branching narrative, leading to multiple endings, adds a layer of depth and encourages players to experiment with different routes to uncover all available content.

How is the map design structured?

The constraint of a 300-line limit per map is a defining characteristic. This technical limitation necessitates creativity in space and detail, often resulting in densely packed and strategically interesting combat arenas. The collaborative nature of map creation means players can expect a variety of design philosophies and aesthetic styles throughout the mod.

What content can players expect?

The mod features four primary maps, with the majority offering both "naughty" and "nice" variations. This effectively provides players with up to seven distinct playable map experiences. The thematic differences between the "naughty" and "nice" versions extend beyond mere aesthetics, often incorporating altered enemy encounters and environmental hazards to further differentiate the gameplay.
