Q3 Center heeft een artikeltje in elkaar gedraaid met een opsomming van alles wat nieuw is in Quake3:
This article is intended for two audiences: Those who have not been able to play q3test (like Bigdog) and those who have played, but are looking for a summary of what's new and may not have noticed some of these things. Please email either Mobius Trip or Nechaboi if you notice any cool new details that we missed. John Carmack said that because they were developing multiplayer only, they could focus on the details of things that would occur over and over again. I have to say that he has lived up to his words because the details are amazing! Clicking on a screenshot will open it in a new window. From then on all screenshots will open in that window, so make sure you check it when you click on a new screenshot link.
