The classic shooter Quake has received a new coat of paint and been re-released for free as Quake Live by ID, its original developer.
Bugs might still appear since Quake Live is still in beta, but these are minimal since it's a simple game. A valid email address is required to register before installation. There is no charge to download or play.
The games themselves are played online with deep community features included in the game. Find friends and invite them to your game or join theirs, or just work your way up the global leaderboards to take the top spot.
An interesting block-style game!
