About Deck & Conn

Step into a chilling alternate 1989, where your nuclear-powered corvette serves as both your ship and your lifeline in an endless Cold War conflict that has spilled into deep space. This game merges the stark aesthetics of retro computer wargames with a command experience that emphasizes tension and strategic decision-making. Rather than flashy space battles, you engage in calculated naval-style skirmishes, relying on instruments and reports to navigate through uncertainty.

Gameplay revolves around meticulous turn planning, managing your ship’s limited resources, and deciding when to engage or retreat against enemies. Each decision carries significant weight, impacting your campaign and the fate of your crew. With a dynamic career mode and tailored scenarios for practicing tactics, the game delivers depth in its approach to resource-driven survival. It's ideal for players who appreciate thoughtful turn-based strategy and the nostalgic charm of classic wargames.

  2. Extract or Run Setup: Extract the archive to a dedicated games folder using 7-Zip or WinRAR (avoid installing inside restricted system folders like C:\Program Files).
  3. Verify Dependencies: If prompted on first launch, install the bundled DirectX, Visual C++ Redistributables, and .NET runtime packages located in the _CommonRedist folder.
  4. Launch as Administrator: Right-click the main game executable and choose Run as administrator so local save files and configuration profiles write cleanly.

  • Missing DLL or Black Screen on Launch: Install both vc_redist.x64.exe and vc_redist.x86.exe, update your GPU drivers, and add the game folder to your Windows Defender exclusion list so real-time scanning does not quarantine game binaries.
