Quake Live is a first-person shooter video game by id Software designed to run on x86-based computers running Microsoft Windows, Mac OS X or Linux that is downloaded and launched via a web browser plugin. Quake Live is free to download and play.
In addition to usability changes, Quake Live has a new, more streamlined HUD. The game is also censored to remove blood, gore, and satanic references that were found in Quake III Arena and is the only game in the series that was developed by id Software internally to be rated T by the ESRB.
