Browsing the internet I ended up with a deparano news that I've provided a certain time according to the speed of the internet soon there will be more nescessário install on pc, so I do not expect that to happen so fast.

I present to you Quake Live

Is a series of Quake FPS with great renown, always looking for innovations in their releases. When it appeared, with a dynamic and explosive style, captivated countless fans around the world. The number of players, each version will only grow. See the example of Quake Live: all the adrenaline you already know, a game full and free, that runs within its own Internet browser. It is both a temptation and play it.

And do not go thinking that your internet will slow down it works the same way as if its net installed and used also as the game installed on your pc

The game requires a Punkbuster anti-cheat plugin and a pro if I use firefox
