"Highly compressed" versions of Call of Duty: Black Ops (often 7GB–12GB) are popular for reducing download size, though they require long installation times and high CPU usage for decompression. These versions are usually intended for offline play, with risks of malware from unofficial sources, but maintain the full single-player campaign and zombies content.
