About This Game

Project II: Silent Valley is part of the experimental 计划 Projects series, which consists solely of Chicago Project and Project II: Silent Valley. Both are standalone narratives, and no knowledge of the other title is required to play this game. If characters or names from 计划 Projects appear again in other works by the creator, they should be regarded as separate reinterpretations.

CG/Video Playback Optimization

You can now choose from three different Windows video playback modes in Settings, allowing you to switch based on your device configuration:

  • Default / Media Foundation: The recommended default option. Supports hardware decoding and generally provides good performance and compatibility on most Windows devices.

  • Compatibility / DirectShow: A traditional Windows playback mode that may offer better compatibility with certain video formats or codec environments. If you encounter playback issues with the default mode, try this option.

  • Streaming / WinRT: A newer Windows playback mode with better support for streaming media. You can also try this option if the default mode causes stuttering or compatibility issues.

If videos in the game experience noticeable stuttering, black screens, or other playback issues, we recommend switching to a different playback mode in Settings to find the option that works best for your device.

In this dystopian parallel America, the “Nodomain Consortium (N.C.)” has overthrown the traditional government. The current United States is divided between two major powers: the militarized "N.C. Government," which controls most regions with an iron grip, and the remnants of the former regime, known as the "Old Government." Beneath the surface of peaceful coexistence, a fierce power struggle is intensifying… In this world dominated by alienation and authoritarianism, how will you, as a reformist, make your choices?

  • A visually striking near-future aesthetic
    A carefully crafted blend of Brutalism, retro-futurism, and Wabi-sabi design styles brings each region to life with its own unique and harmonious visual identity. Complemented by custom-composed regional soundtracks, the result is a truly immersive experience with no repetition.

  • Deeply developed character ensemble
    From a seemingly submissive special ops soldier to a sharp, enigmatic base commander bound by duty, each character hides a layered emotional core and a captivating backstory—waiting for players to uncover.

  • Rich world exploration
    Discover hidden character dialogues, classified documents, and military files during your freeform exploration. Every room conceals forgotten secrets, and your deputy Osprey will provide professional analysis of all materials you collect.
