7-zip is required to extract this file. Just make an empty directory named Daikatana and extract the contents and run Daikatana.exe to play the game. I recommend setting your character to Mikiko in the Multiplayer menu. Her statistics are +1 attack, +1 speed. This makes her moves a lot faster compared to the other characters and a lot of the more skilled players all use Mikiko.
