How To Install And Play Fallout: London On Steam Or GOG

Fallout: London represents one of the most ambitious modding projects in recent gaming history, transforming the Commonwealth setting into a completely reimagined post-apocalyptic British capital. This comprehensive modification introduces an entirely new gaming environment that demands specific technical prerequisites for optimal performance.

The installation process for this groundbreaking mod differs significantly from standard Fallout 4 modifications due to its massive scale and complex integration requirements. Understanding these distinctions upfront will save you considerable time and frustration during the setup phase.

This expansive modification emerges after extensive development cycles and creative challenges, particularly following Bethesda’s controversial Next-Gen update that initially disrupted compatibility. Players can anticipate a fundamentally different gaming experience featuring a completely redesigned map layout, professionally voice-acted characters, multiple branching narrative paths, and sophisticated faction dynamics.

Before attempting installation, ensure you meet these critical technical prerequisites:

• You must possess a legitimate copy of Fallout 4 through either Steam or GOG distribution platforms
• Complete DLC ownership is mandatory, including Automatron, Far Harbor, Nuka World, Wasteland Workshop, Contraptions Workshop, and Vault-Tec Workshop
• Steam platform users specifically need to revert their game version to 1.10.163.0 to circumvent Next-Gen Update incompatibilities

GOG platform users benefit from the most straightforward installation pathway, thanks to the mod development team’s official partnership with the digital distribution service. This collaboration eliminates the version downgrade requirement that complicates Steam installations, providing immediate compatibility right out of the gate.

When acquiring Fallout 4 through GOG, prioritize the Game of the Year Edition which currently retails at approximately $16 during promotional periods – representing substantial savings over standard pricing. This edition includes all necessary DLC content automatically, streamlining the verification process.

The installation workflow requires downloading the GOG Galaxy client, which serves as the centralized hub for both Fallout 4 and the London modification. This integrated approach minimizes file path errors and ensures proper mod registration within the game’s architecture.

Post-installation, launch the modification directly through the GOG Galaxy interface rather than standard game executables. This guarantees all dependency checks and compatibility validations occur automatically before gameplay initiation.

Steam installations present additional complexity due to the automatic Next-Gen Update deployment that conflicts with Fallout: London’s framework. The modification specifically requires version 1.10.163.0 for stable operation, necessitating manual version reversion procedures.

To downgrade your Steam installation effectively, navigate to Fallout 4’s properties menu, access the Betas tab, and select the ‘1.10.163.0 – Next-Gen Update Opt-Out’ option. This process typically requires 15-30 minutes depending on your internet connection speed and may consume 5-10GB of additional disk space during the transition.

Post-downgrade, verify file integrity through Steam’s validation system to ensure no corruption occurred during the version rollback process. This critical step prevents runtime crashes and mod initialization failures that could compromise your gaming experience.

Alternative installation methods include utilizing community-developed downgrade patchers available through modding communities, though these carry additional compatibility risks and lack official support from the London development team.

Many players encounter version mismatch errors where the game automatically updates despite manual downgrade attempts. To prevent this, disable automatic updates in Steam settings and launch the game exclusively through mod organizers rather than Steam’s interface.

Performance optimization recommendations include allocating at least 8GB of system RAM specifically for Fallout 4 processes and utilizing SSD storage to reduce loading times across London’s expansive map areas.

Before beginning installation, create comprehensive backups of your existing save files and mod configurations. The London modification fundamentally alters game mechanics and world spaces, potentially rendering previous saves incompatible.

Troubleshooting common crashes involves verifying that all DLC content loads properly before the mod activates. Load order management proves critical – position Fallout: London below all official DLC but above any cosmetic or gameplay tweaks in your mod manager’s load sequence.

Action Checklist

• Verify ownership of all Fallout 4 DLC content through your platform’s library
• Backup existing save files and mod configurations to prevent data loss
• Downgrade Steam version to 1.10.163.0 or confirm GOG Game of the Year Edition compatibility
• Install GOG Galaxy client if using GOG platform for streamlined mod management
• Download Fallout: London through official channels and verify file integrity
• Configure mod load order with Fallout: London positioned below official DLC
