John Romero's Daikatana

The player must lead this team, interacting with them to guide them through perilous worlds, exploring vast levels that are filled with an array of intelligent enemies.
In their quest to save history, players will journey through four different time periods, traveling from mythical Greece to a post apocalyptic San Francisco 500 years in the future. Battling over 60 different monstrous enemies with more than 30 different weapon types, breaching obstacles and unearthing secret locations.
