Quake live, A First Person Shooter on a Browser has a relatively high chance of being a HUGE success.
If you are at work, this is gonna be what gamers play. Screw flash games. However, here at TechXav, we don’t play games while at work
All jokes aside, I got a chance to try this out and it is responsive. Quake is one of the founding fathers in First person shooters that everyone plays now and is made by the famous id software. It shaped first person shooters to what it is now with help from Doom and Halo.
Give it a try
