He has worked on ever single title that Bungie Studios has produced since the game Myth II: Chimera was developed. He played a major role in developing the campaign of Halo: Combat Evolved and the multiplayer sides of Halo 2, Halo 3, and the upcoming title Halo: Reach.
As for his style and mentality, Tyson has a strong understanding of how to create games that cater not only to hardcore gamers but also casual gamers. In an interview around the release of Halo 2 Tyson said this:
"Fundamentally, know thy audience. Is your target broad appeal and a casual audience? Then level out your learning curve, beware of unnecessary complexity, and keep the required time investment short. If you're comfortable targeting a more hardcore audience, then you can make your learning curve steeper, and add some complexity to the game that gives it longevity. But when you design a game for the hardcore, but try to pass it off to casual gamers, it's a disaster! The casual gamers don't want to play an hour long game, and the hardcore players resent the dumbing down" -Tyson Green
This ideology helped to make Halo 2 and its successors some of the most widely played games that modern consoles have to offer.

There is very little information on Tyson Green and his life other than the projects he has worked on. This is probably a result of the fact that video game designers are not as well known as the companies they work for. He has worked for the game developer Bungie Studios long enough to have earned himself the rank of "Grizzled Ancient." This is a rank that the studio gives to anyone who has worked there since the studio was first getting underway.
