Story Summary / Plot Overview

Piece together Marathon Infinity's fractured timeline and prevent the W'rkncacnter's awakening through terminal entries and environmental clues.

Marathon Infinity plunges You into a fractured timeline, a direct consequence of the events in Marathon 2: Durandal. The narrative is non-linear, forcing You to piece together the overarching story through terminal entries and environmental clues. Your primary objective, as the unnamed Security Officer, is to prevent the awakening of the W'rkncacnter, an ancient, chaotic entity that threatens to unravel reality itself.

The game begins with the Security Officer being transported through various alternate realities and time periods by Durandal, the rogue AI. Durandal's goal is to find a way to stop the W'rkncacnter, which was inadvertently released during the destruction of the S'pht home world, Lh'owon, at the end of Marathon 2. This leads to a series of missions that often feel disjointed but are all critical to understanding the larger threat.

Early Missions: Understanding the Threat

Your initial deployments serve to introduce the fragmented nature of the timeline and the immediate dangers. Expect to encounter familiar foes like the Pfhor and the S'pht, but often in unexpected contexts.

• "Ne Cede Malis": This opening level often places you in a chaotic, war-torn environment. Focus on survival and familiarizing yourself with the M1 Garand and the Shotgun, which are usually readily available. Your immediate goal is to reach the first terminal to receive Durandal's initial, cryptic instructions regarding the W'rkncacnter.
• "Try Again": This level frequently features a heavy Pfhor presence. Prioritize conserving ammunition for your Assault Rifle and Fusion Pistol. Look for hidden caches of 2x Recharger units, often tucked away in ventilation shafts or behind destructible walls, to keep your shields up.
• "Fatum Iustum Stultorum": This level often involves navigating complex, multi-layered environments. The key here is to locate and activate specific switches or pressure plates that open new pathways. Be wary of ambush points, especially around teleporter exits. The "Double Aught Term" mentioned in some guides is a critical information point here, often found in a secluded room accessible after solving a minor environmental puzzle.

Mid-Game: Gathering Information and Resources

As you progress, the missions become more focused on specific objectives related to the W'rkncacnter and the efforts to contain it. You'll often be tasked with retrieving data, activating ancient S'pht technology, or eliminating key threats.

• "Aye Mak Sikur": This level is crucial for understanding the S'pht's ancient knowledge regarding the W'rkncacnter. You'll need to navigate through S'pht ruins, often guarded by powerful Juggernauts. The "Double Aught Term" here provides vital lore and sometimes even a hint for a future objective. Ensure you have a plentiful supply of Rockets for these encounters.
• "Thing What Kicks": This mission often involves a race against time or a powerful, unique enemy. A common strategy involves utilizing the environment to your advantage, such as luring enemies into traps or narrow corridors where your Shotgun is most effective. Keep an eye out for secret areas containing health power-ups or extra ammo for your SPNKR Rocket Launcher.
• "La Cosa Nos": This level frequently involves disabling Pfhor systems or retrieving a specific artifact. Secrets in this level often involve finding hidden switches that open up new areas with valuable weapon upgrades or shield rechargers. The Plasma Rifle is particularly effective against the armored Pfhor encountered here.

Late Game: Confronting the W'rkncacnter

The final stages of Marathon Infinity are a desperate struggle to prevent the W'rkncacnter's full awakening. The levels become increasingly challenging, with more powerful enemies and complex objectives.

• "Yugeon": This level often serves as a direct confrontation with the W'rkncacnter's influence, manifesting as distorted environments and powerful, mutated enemies. Your primary goal is typically to activate a device or reach a specific location to disrupt the entity's power. Conserve your Magnum ammunition for critical hits against high-health targets.
• "Where Some Rarely Go": This mission often involves navigating a treacherous, alien landscape. Expect environmental hazards and relentless enemy waves. The key to survival is often finding a safe vantage point and utilizing long-range weapons like the Sniper Rifle or the Plasma Rifle's secondary fire.
• "Pfhoraphobia": The penultimate level often involves a final push against the Pfhor forces attempting to exploit or control the W'rkncacnter. You'll need to clear out multiple enemy strongholds. Ensure you have full health and shields, and consider using your Grenade Launcher for crowd control.
• "Carnage Circus": The final confrontation. This level is a gauntlet designed to test all your skills. The objective is to prevent the W'rkncacnter from fully manifesting, often by activating a series of ancient S'pht devices or destroying its physical anchors. Focus fire on the W'rkncacnter's manifestations, utilizing all your available heavy weaponry, especially the SPNKR Rocket Launcher and the Fusion Pistol's overcharge ability. The ending is often ambiguous, leaving You to ponder the true outcome of their actions across the fractured realities.
