Daikatana is a 3D first-person action game developed by ION Storm. Daikatana contains a unique story, a vast amount of diverse environments to explore, ranging through 4 different time zones. It includes an enormous amount of enemies, weapons, 2 Artificial Intelligence(AI) Sidekicks, and spectacular 3D-accelerated graphics.
That's a full-standalone multiplayer built of Daikatana, approved by John Romero to be shared with the public. It was created by "The EO" and .petroid". It's worth a download, there are still servers. Enlarge for more information.
John Romero: "It’s taken a while but The EO and .petroid have done something pretty cool: they stripped Daikatana down to the smallest size possible for playing deathmatch, 114mb total download. I tried it out and it worked perfectly. There’s been some modification of lots of little things and it has a great little launcher included to simplify some options. I connected to a master server and found about 5 of them running and people were DMing so I joined and it was tough to stop!"
