The original Crysis Warhead installation can hover around 6GB to 8GB depending on the version. A high-quality repack compresses the game assets significantly, stripping out unnecessary foreign language audio files and redundant "redist" files (DirectX installers, etc.).
Ensure you have at least 2 GB of free RAM and 8 GB of HDD space available for the installation process. crysis warhead v111711repack best
