CSZ feels like a last minute edition, like they were originally just going to make it an alt costume for sub-zero, but decided to get ambitious at the last moment in development, so we got a really half assed character with no alt, broken ending, and a weird mixture of cyrax and sub-zero. It feels awkward to play, and his moves don't really jell that well, thankfully he has awesome strings and really good dive kicks, otherwise he would be completely worthless.
