This is a computer animated fan film starring characters from two different franchises: The video game "Tomb Raider" and the anime "Iria Zeiram".
Likely due to copyright reasons, Lara Croft is named "Tara Croft" in the end credits.
This is a fan made clip designed for an ancient 3D CGI gallery which showcased amateur works back when the Internet was young. The animator created this, kind of as a dare, in his bedroom using a very slow Pentium III PC. It does look dated, because it wasn't state of the art back then in 2000. At the time he complained about not having reasonable equipment; his machine was more or less suitable for light web browsing. There's a Director's Cut on YouTube and there's also an old Geocities site if you do a search for Jedi3167.
