Hiro Miyamoto is a martial arts instructor and a member of an ancient clan of fighters. One day he learns that Kage Mishima, a sworn enemy of his clan, has gained possession of the Daikatana, a magical sword that allows its bearer to travel through time. As a result of Mishima's quest for power, a devastating disease is threatening humanity. Hiro and his friends must venture into different time periods, retrieve the sword, and defeat Mishima.

Daikatana is a first-person shooter using the Quake II engine. The game is divided into four episodes of several levels each, each episode taking place in a different time period: far-future Japan, ancient Greece, Dark Ages Norway, and near-future USA. The game uses cutscenes and text to tell the story. Two AI-controlled characters accompany Hiro throughout the quest, helping him in battles and also requiring protection. In addition to several different firearms, the Daikatana itself, which the player acquires in Episode 2, can gain experience and grow stronger as it is used. The game includes a multi-player deathmatch mode.

It can only install and running on WIN95/98 compatibility mode
