This is a modification for Doom II: Hell on Earth, released on April 7, 1996, for PC (Microsoft Windows). It offers a unique twist on the classic shooter formula by transporting players through different historical eras to combat an otherworldly threat. As a UAC agent, your mission is to prevent interdimensional beasts from altering history using a stolen time-travel device. The core experience revolves around navigating five distinct levels, each representing a different time period or locale, to eliminate these temporal invaders and preserve the timeline.

The Temporal Threat

The narrative places you in the role of a UAC agent tasked with a critical mission: to travel through time and stop the spread of demonic entities that have acquired the means for temporal displacement. These creatures are not just a localized problem; their actions threaten to create catastrophic ripples across history, potentially erasing existence as we know it. Your objective is to venture into five distinct historical periods, confronting these beasts and neutralizing the threat before it irrevocably alters the course of human civilization.

Core Gameplay and Unique Features

As a modification, this game leverages the established engine and mechanics of Doom II: Hell on Earth, providing a familiar yet fresh shooting experience. The primary innovation lies in its level design and thematic progression. Each of the five episodes is meticulously crafted to reflect a different time period or geographical setting, offering a diverse range of environments and challenges. This temporal journey means players will encounter varied visual aesthetics and potentially different enemy placements or environmental hazards tailored to each era. The gameplay remains focused on fast-paced, arena-style combat, requiring players to utilize their arsenal effectively to overcome waves of enemies and achieve mission objectives within each historical setting.

What makes this game unique?

The standout feature of this modification is its ambitious concept of time travel integrated into the classic Doom gameplay loop. Instead of a singular, continuous environment, players are presented with a series of self-contained episodes, each a distinct journey into a different historical epoch. This approach allows for a broader exploration of themes and visual styles within the confines of the Doom engine, offering a varied experience that goes beyond the typical level progression found in many mods. The narrative premise of preventing historical distortion adds a compelling layer to the action, framing each firefight as a crucial battle for the fate of time itself.

Technical Details and Release

This modification was developed and released for the PC platform, specifically for Microsoft Windows, in 1996. It requires the original Doom II: Hell on Earth to be played, as is common for many game modifications that build upon existing game engines and assets.
