If you're interested in doing so, get in touch with us. +The aim of this project is to reverse GTA Liberty City Stories. ## How can I try it? -- reVC requires game assets to work, so you **must** own [a copy of GTA Vice City](https://store.steampowered.com/app/12110/Grand_Theft_Auto_Vice_City/). -- Build reVC or download the latest nightly build: - - [Windows D3D9 MSS 32bit](https://nightly.link/GTAmodding/re3/workflows/reVC_msvc_x86/miami/reVC_Release_win-x86-librw_d3d9-mss.zip) - - [Windows D3D9 64bit](https://nightly.link/GTAmodding/re3/workflows/reVC_msvc_amd64/miami/reVC_Release_win-amd64-librw_d3d9-oal.zip) - - [Windows OpenGL 64bit](https://nightly.link/GTAmodding/re3/workflows/reVC_msvc_amd64/miami/reVC_Release_win-amd64-librw_gl3_glfw-oal.zip) - - [Linux 64bit](https://nightly.link/GTAmodding/re3/workflows/build-cmake-conan/miami/ubuntu-latest-gl3.zip) - - [MacOS 64bit](https://nightly.link/GTAmodding/re3/workflows/build-cmake-conan/miami/macos-latest-gl3.zip) -- Extract the downloaded zip over your GTA VC directory and run reVC.
