Captain Grant Sims commands the Protocol military division stationed in Atomfall’s Wyndham Village, operating from their fortified headquarters. Despite his intimidating presence and the chaos his forces have brought to the region, strategic cooperation can transform him from adversary to ally. Building rapport with Sims unlocks exclusive intelligence about Quarantine Zone evacuation paths, though his ultimate motivations remain shrouded in mystery.

This comprehensive guide details the complete Captain Sims investigation chain, including critical decision points and the significant gameplay advantages gained through Protocol collaboration.

Your first objective involves locating Captain Sims at Village Hill, situated centrally in Wyndham Village just north of St. Katherine’s Church. Protocol soldiers will direct you immediately upon entering the village perimeter.

Inside Village Hall’s main chamber, you’ll find Captain Sims positioned authoritatively behind his command desk. Initial interactions will be guarded and suspicious, requiring deliberate trust-building actions to progress the relationship.

To establish credibility with Protocol leadership, you must complete one of two available investigative assignments within Wyndham Village. Both missions serve as proving grounds for your capabilities and loyalty assessment.

The first option investigates a homicide at St. Katherine’s Church, launching the “Murder in the Church” questline. This investigation typically requires 20-25 minutes to complete thoroughly and features multiple resolution possibilities affecting local faction reputation.

Alternatively, the bakery investigation focuses on strange behavioral patterns exhibited by the baker’s husband. This shorter mission (15-20 minutes) involves surveillance and evidence gathering with fewer combat encounters than the church alternative.

Strategic Tip: Choose the bakery investigation if prioritizing speed, or the church investigation for greater experience points and loot opportunities. The church mission provides approximately 35% more resource rewards but requires dealing with hostile entities.

Upon completing either investigation, return to Captain Sims with your findings. This initial success establishes foundational trust, though he remains cautious and immediately assigns a more significant challenge to test your commitment.

Captain Sims’ next assignment involves interrogating Dr. Garrow, the scientist responsible for establishing the Quarantine Zone boundaries. She’s currently detained at Skethermoor Prison after attempting escape using experimental technology.

Critical Advantage: Approaching Dr. Garrow through Captain Sims provides authorized prison access, eliminating the need for stealth infiltration or combat with perimeter guards. This approach saves 40-50 minutes compared to unauthorized entry methods.

Unlike standard prison infiltration requiring Signal Redirector equipment and tactical engagement with multiple guard patrols, Protocol authorization grants direct passage through security checkpoints.

Common Mistake: Many players attempt prison entry before establishing Protocol relations, resulting in unnecessary combat and resource expenditure. The Sims-authorized approach bypasses approximately 85% of prison exterior resistance.

Once inside, locate Dr. Garrow in her containment cell. The interrogation reveals crucial backstory about Atomfall’s quarantine origins and the mysterious device she attempted to use for escape.

With Dr. Garrow’s intelligence secured, Captain Sims deploys you on critical Protocol operations requiring specialized skills. These missions demonstrate the tangible benefits of military alliance.

The radio component recovery mission in Casterfell Woods involves navigating irradiated zones and hostile wildlife. Pro Tip: Equip radiation-resistant gear and bring EMP devices to disable automated security systems protecting the component.

Infiltration of the Oberon Digsite represents the climax of Protocol collaboration. This heavily fortified location requires both combat proficiency and puzzle-solving abilities to access restricted areas.

The final confrontation with Oberon provides multiple resolution options. Choosing to destroy the entity and escape with Protocol forces unlocks exclusive military-grade equipment and establishes permanent alliance status.

Advanced Strategy: Complete these missions efficiently by consulting our Weapons Unlock guide for optimal loadout configuration against digsite security systems.

The Captain Sims investigation chain culminates in significant narrative branching with lasting gameplay consequences. Alliance with Protocol provides strategic advantages unavailable through other faction alignments.

Trust Mechanics: Your decisions throughout the investigation directly impact Sims’ willingness to share intelligence and provide military support. Maintaining Protocol favor requires consistent demonstration of loyalty and capability.

The alternative escape routes revealed through this alliance offer safer passage through contaminated zones and reduced interaction with hostile factions.

Long-term Impact: Choosing the Protocol ending affects subsequent playthrough opportunities, including access to restricted technology and specialized military training programs.

For players considering multiple faction approaches, our Complete Guide details comparative benefits across all major story paths.

Optimization Note: The Protocol path synergizes effectively with assault Class Guide builds, providing enhanced combat effectiveness in late-game scenarios.
